Find Distance Between Two Points

Find Distance Between Two Points To find the distance between two points whose co-ordinates are given. Let P1 and P2 are the two given points, and let their co-ordinates are respectively (x1 y1) and (x2 y2).Therefore, by trigonometry we can find that the distance between two points is given by the formula The distance P1 P2 = [(x1 x2)2 + (y1 y2)2] Note :The distance of the point (x1, y1) from the origin is (x12 + y12) because the coordinates of the origin are (0, 0). The axes are rectangular. Example1 :Let us find the distance between the pairs of points (2, 3) and (5, 7). Solution :We have to find the distance between the pairs of points (2, 3) and (5, 7). Let x1 = 2, y1 = 3 and x2 = 5, y2 = 7 Hence required distance = (x1 x2)2 + (y1 y2)2 = (2 - 5)2 + (3 7)2 = (-3)2 + (-4)2 = 9 + 16 = 25 = 5 The distance between two points = 5 Example 2.Find the distance between the pairs of points (-3,-2) and (-6, 7) The axes are being inclined at 600. Let x1 = -3, y1 = -2 and x2 = -6, y2 = 7 and q = 600 Hence required distance = (x1 x2)2 + (y1 y2)2 +2 (x1 x2) (y1 y2) Cos q = (-3 + 6)2 + (-2-7)2 +2(-3+6) (-2-7) Cos 600 = (3)2 + (-9)2 + 2 (3) (-9). 1/2 The distance = 9 + 81 - 27 = 63 = 37.

5 Misconceptions About Introverts - Introvert Whisperer

Introvert Whisperer / 5 Misconceptions About Introverts - Introvert Whisperer 5 Misconceptions About Introverts If you are somebody who is not naturally very outspoken or conversational in a group and who focuses more inwardly on your thoughts, you will know how easy it can be for outgoing colleagues to make assumptions about you as a person. Unfortunately, these can often be negative. This can be half the issue for people with introverted qualities, as you can often end up feeling misunderstood by your more extroverted colleagues. Here’s a roundup of some of the misconceptions around what introverts are like, the myth busters to put them straight and how you, as an introvert, can benefit your employer with these myth-busting qualities. 1. Introverts are shy and don’t say much. How many times have you heard colleagues tell you ‘oh, you’re so quiet’ or ‘I didn’t notice you were there’ because you’re so quiet’? Sound familiar? It is unfortunate that many people associate being quiet with being shy or unsure, when the two are entirely different things. Shy people tend to have less confidence and may be reluctant to go out in a group or take a while to work up the courage to express their opinion â€" yes, this will make them quiet. However, you can be quiet and yet still be confident, which is often the case if you have introverted qualities. It has been proven that, although introverts say less than their more extroverted counterparts, when they do speak it is a point that gives real value and insight. Benefit to Employer: Managers, get ready for the moment when your introverted staff member comes out with a statement that will prove valuable and will make the team sit up and think from a new perspective. 2. They do not like to socialize. It isn’t true that introverted people don’t like to socialize, but they don’t like to do it for as long as some other people. This is to do with their dopamine levels â€" the chemical connected to the feel-good factor in the brain. A study has shown that the science behind this is that the brains of introverted people are such that their dopamine levels are higher than extroverts and, as such, do not require as much of the ‘feel-good’ factor though socializing. The other point is that introverts prefer to socialize in small groups of people, or on a one-to-one basis, where they feel they can really connect with somebody and have a meaningful conversation. Many introverts also like to get their stimulation and excitement through hobbies, reading or in their own company in the comfort of their own surroundings. Scott Barry Kaufman, in Scientific American, highlights that extroverted people are motivated by conversation and interaction with others, whereas introverts are less motivated by that. While it may appear that introverted people don’t like to socialize because they don’t talk as much in the office, it may actually be because they become more easily over-stimulated than other people. Benefit to Employer: While your outgoing co-workers are busy gossiping about the latest co-worker’s business, you are quietly getting on with your work and will have the task done in time for the manager’s deadline! 3. Introverts Like to be Alone. Introverts are quite comfortable with their alone time and having time to tune into their own thoughts, but this doesn’t mean to say that introverts don’t like being around other people. In fact, they crave the company of others with the same interests as them and those they can discover the world with or share their innermost thoughts. Extroverts are more stimulated by outside conversations and banter. If alone for too long, extroverts may quickly become restless or bored and actively need that interaction with others. The reason behind introverts being happier in their own company may be because they have a naturally higher ‘arousal’ level embedded in their brains, according to the 1960s researcher, Hans Eysenck. This means that when in a group of people, they can quickly feel over-stimulated. Extroverts, on the other hand, have a lower ‘arousal’ level, meaning they have more of a need to seek stimulation from the outside world to achieve the same levels. Benefit to Employer: In team meetings, it may seem like the introverted person is quiet and has nothing to contribute, but the truth is, they are being internally stimulated and are carefully thinking through the ideas being generated. Assume that the introverted team member will come back to you for sure t a later time with their ideas. 4. Introverts Cannot Be Leaders in the Workplace. Don’t underestimate this one. There seems to be some common belief that those in a senior or managerial role must be loud, outspoken or immediately decisive to be effective at running a team. Sure, introverts may appear quieter and take longer to process information, but that doesn’t mean they do not have the confidence to chair team meetings, take on senior tasks or even make decisions on projects. There are many successful leaders in different industries who, while being good at what they do, also take a more thought-processing and introverted approach to their way of working. Barack Obama and Bill Gates are both said to have introverted qualities who communicate with great passion about what they do. Benefit to Employer: Well-thought out decisions when it comes to moving forward as a team, knowing that they have taken the time to come up with a strategic and detailed plan. 5. They Don’t Like to Talk. Again, it’s not that introverted people don’t like to talk â€" the leaders above disprove this myth. It’s just that, where there may be times when introverts talk less, it means they are listening more. Some talkative people can be so chatty that they don’t make the time to really listen to what the other participants in the conversation are saying. With introverts, the internal part of their mind is switched on and they are taking in everything going on around them, enabling their thoughts to gradually develop into opinions and ideas. Benefit to Employer: Introverts have proven to be great at skills such as writing and researching, which means they are more often than not capable of taking on these types of tasks!

How To Write a Song Today 4 Easy Steps

How To Write a Song Today 4 Easy Steps Sign up successful 1. Play chords or a riff. Play chords that you know sound good together. You can use what you know of music theory to help think of possible chords. One of the most common chord progressions is I, IV, V, which would be C, F, G in the key of C. Another approach is to forget about all that theory and just play chords that sound new and good to your ears. This is a great way to make a song sound like your own. 2. Sing or hum over the harmony. Start by singing syllables without words. When Paul McCartney originally wrote “Yesterday,” instead of saying “all my troubles seem so far away,” he sang “Scrambled eggs, oh my darling you’ve got lovely legs.” Likewise, when Stevie Wonder first wrote “Superstition,” instead of singing “writing on the wall,” he sang “wash your face and hands.” If they write lyrics this way, so can you! Then once you have a basic melody, it can be much easier to add lyrics. 3. Repeat steps 1-2 to form a chorus and then a bridge. Here is a general breakdown for what each section of your song should look like: Verse: The verse should tell a story. Use it to describe a scene, an emotion, or something in detail. This section can rhyme but it doesn’t have to. Chorus: The chorus should be very simple and repetitive. Try to make a hook that people can‘t get out of their heads. Here are a few examples of songs with memorable choruses: Beatles All You Need Is Love; Carly Rae Jepsen Call Me Maybe; Eric Clapton Layla Bridge: The bridge is a common addition to a song that keeps the listener engaged by going into new territory. It‘s often used as an instrumental section where solos can occur. Changes in the chords, key, tempo, dynamics, or instrumentation are common. Here are two additional song sections that are commonly used: Pre-Chorus: The pre-chorus is typically a transition between the verse and chorus. Another approach can be to use the pre-chorus in place of a chorus for the first half of a song. This allows you to save the chorus for a big climax toward the end. Intro and Outro: Intros and outros can be instrumentals or feature lyrics that introduce or develop the main idea of the song. 4. Place the song sections in this order: Verse, Chorus, Verse, Chorus, Bridge, Chorus This is a very common structure for pop songs. Examples of songs that use this structure are: Otis Redding Dock of the Bay; Incubus Drive; John C. Mellencamp Jack and Diane By playing chords, singing over them, making multiple sections, and finally ordering these sections, you can quickly and easily write a song today! Congratulations! As you continue to write, avoid writer’s block by doing these steps without judging yourself and your abilities. You can do it. Happy songwriting! Learn more: Check out our guide to songwriting!

ACT Prep

Huntington Learning Center Offers Advice for Effective SAT/ACT Prep Its that time of year when many college-bound students are taking or re-taking the SAT and ACT. Co-Founder Eileen Huntingtonof Huntington Learning Center says that the best way for students to prepare for college entrance exams is through plenty of practice. It is true that keeping up with school work inherently helps students acquire the knowledge that they need to perform on college entrance exams, but there is no substitute for regular, thorough studying of the types of questions they will see on these tests, says Huntington. Shesuggests that parents think about the following as they and their teens develop a summer study schedule that will yield positive results: Learn the ins and outs of each exam. Teens should get to know the format and details of the exam they decide to take. Its essential to understand what is expected on the test, the time limit for each section, the number of questions, and other basic information. This can help steer teens toward one exam over the other. Some of the major distinctions that could also impact a test-takers decision between the exams: The ACT has a Science Test that tests critical thinking skills (while the SAT does not). The SAT has one more reading passage than the ACT. The SAT has some math questions that must be answered without the use of a calculator (the ACT allows the use of a calculator for all math questions). Take a diagnostic evaluation. A teens very first step to devising an effective SAT/ACT prep plan should be taking an initial test to determine his or her strengths and weaknesses. Study sessions will be far more effective when teens know exactly what to study and where they need to improve. A full-length diagnostic test gives a baseline so that teens can identify areas to focus on (and measure their progress). Create a schedule. Teens will be more effective in their study approach if they create a schedule with milestones. The schedule should dedicate the appropriate amount of time to each subject and specific section of the exam, targeting weaker areas and considering teens strengths. Certainly, a teens specific test score goals (possibly driven by his or her target college or university) and the gap between the diagnostic test score and goal test score will impact the amount of study time needed. Cover all the elements. Yes, the SAT and ACT require subject-matter knowledgethis should be the foremost area of focus in a teens study plan. However, the best study plan should cover several other areas as well: Practice exams Teens should take at least two full-length, timed practice tests that simulate the actual test environment. Speed work There are a lot of questions on the SAT and ACT to answer in a short timeframe. Its important to work on improving ones speed without sacrificing accuracy. Stress management Theres no getting around the fact that the SAT and ACT can cause teens anxiety because of the impact that the exams can have on their future. Its important that teens learn how to manage any stress and are able to employ relaxation techniques as needed. Plan ahead for a retake. Many teens take the SAT or ACT a few times to attain their best score. Summer before junior year is a good time to prepare for the SAT or ACT. In doing so, keep in mind that many colleges have application deadlines as early as January 1. The SAT is offered seven times per year and includes a summer test in August, and ACT is offered six times per year, with the first test of the school year occurring in September. Its wise to put the best foot forward by adhering to a study plan and schedule because planning ahead for specific test dates is key.

GCSE exam results 2017

GCSE exam results 2017 We would like to wish all our tutees the best of luck today as they receive their GCSE exam results. Our tutors no doubt will also be anxious to hear from parents and students with their good news - hopefully! The team at First Tutors love watching the amazing feedback pouring in from students and parents, whilst many tutors update their tutor profiles with their pupil's results. In a few days time we will be posting some of the best summer feedback comments from happy students this year. Due to the changes in this year's GCSE grading system, this year's results can't be compared with those of previous years according to headteachers. There are now three top grades - 7, 8 and 9 - compared to two under the old system - A* and A - with A* results now split into 8s and 9s. This needs to be taken into consideration when interpreting this year's GCSE national data which reveal: The proportion of GCSE entries receiving grade A/7 or above has fallen 0.5% to 20% compared with last year. Overall in England, Wales and Northern Ireland, passes (grades C/4 and above) dropped 0.6 percentage points to 66.3%. In England, the English literature pass-rate fell 2.5 percentage points to 72%, but in maths it rose from 61.5% to 68.9%. Both are the new, tougher exams. Exam boards revealed that 2,000 extremely able candidates got a 9 in all three new exams. There were 50,000 grade 9s overall - two-thirds of which were girls. For those of you who haven't received the grades they were hoping for, we advise being at the school on results day so that you can talk to your teachers for the best advice. If you need to resit GCSE maths or English these exams are available in November but if you need to resit several subjects you may have to wait until June 2018. If you don't get into sixth form or college perhaps studying A-levels isn't for you but there are other types of qualifications available such as BTECs or City Guilds. If you are thinking of finding a private tutor we are here to help. Now, it's easier than ever to register and create a request to contact as many tutors you wish within in few minutes.
