Learn Section formula
In CBSE Class 10 Mathematics, specifically within the Coordinate Geometry chapter, the Section Formula is an incredibly powerful tool. Imagine you have a straight highway connecting two cities, and you need to build a rest stop exactly one-third of the way along the route. How do you find the exact map coordinates for that stop? The Section Formula helps you pinpoint the exact coordinates of a point that divides a given line segment internally into any specific proportional ratio, moving beyond just slicing it perfectly in half.
The core logic behind the section formula is based on proportional distances mapped along the X and Y axes. If you have a line segment joining two points, A (x₁, y₁) and B (x₂, y₂), and a point P (x, y) divides this segment internally in the ratio m₁ : m₂, you can calculate the exact location of P. The formula states that the x-coordinate of P is x = (m₁x₂ + m₂x₁) / (m₁ + m₂) and the y-coordinate is y = (m₁y₂ + m₂y₁) / (m₁ + m₂). By cross-multiplying the ratios with the coordinates of the opposite endpoints and dividing by the total sum of the ratio parts, you accurately lock in P's position on the Cartesian plane.
Take a close look at the illustrated diagram above. You can observe the line segment connecting points A and B on the coordinate plane, with the green point P breaking the segment into two specific proportional parts represented by the ratios m₁ and m₂. The dashed lines clearly show how point P correlates directly to exact values on the X and Y axes. In your CBSE Class 10 board exams, this concept is a high-yield topic! You will frequently be required to find the coordinates of P given a specific ratio, or conversely, work backward like a detective to discover the unknown ratio m₁ : m₂ when the coordinates of P are already supplied in the question.

Teaching is my profession and passion. I have been providing Tuition at Urbanpro for two years. I have completed a B.E Degree and five years of work experience in a private firm. Apart from this, I have been providing Tuition for two years. I am taking classes from 1st std to 12th Tamil language school curriculum and basics. Social science polity and Computer for class 6th to 12th. Other than this, Major classes are spoken English for kids and Spoken Tamil for people interested in learning a language in India and other countries. My students have successfully completed their language classes in Canada, the USA and Singapore. I love teaching and Tutoring because teachers are the only people without jealousy. I want to help the students achieve their skills in their respective fields. My classes are one-on-one classes, and I sit in sessions with the students and their parents. I provide the materials to the students and conduct the test if they are interested. If you are looking for an excellent professional Teacher who is friendly and dedicated, kindly contact me at Urbanpro. Thank you for searching my profile
My daughter had zero knowledge on tamil grammar for 10 class. I was very happy to have found menaha to help her. She was able ro understand her short comings and trained her well that enanled her to clear her exams. Thank you ma'am.
Hello, my name is Atulya Kumar. I have completed my studies at IIT(ISM)_Dhanbad and I am currently pursuing a PhD at NIT-Rourkela. With a degree in engineering, I am dedicated to teaching. Since 2019, I have been teaching physics to JEE, NEET, and Class XI & XII board students. I take great pride in sharing that my students have achieved exceptional results, with some clearing NEET 2022 with an AIR of 2513 and NEET 2023 with an AIR of 1702. Additionally, many of my students have scored above the 98th percentile in JEE Mains 2023. Teaching physics is a personal challenge for me. I strive to create a comfortable learning environment where students can fully grasp the concepts and apply them effectively during examinations, resulting in excellent marks and ranks.
Mathematics is a subject of understanding in detail by going behind the formula and learning the very basics of it. It's the easiest subject when you understand it. I assure good results with distinctive improvement in maths' understanding.
One of the best physics teacher I've ever come across.Glad to be one of his students. Your expertise in teaching has made physics easy to understand.
I have taught almost 50 students.
The best teacher my daughter have ever got. She can understand everything that she took and also did many question papers. She could write everything that her teacher teaches her and the teacher is very lovely.
My teaching exp.11 year in most reputed coaching in india. Mentor of jee top rank air-12 yatis agrawal, 19, 28 many more in top 100 in jee adavnced. Many of students got 100%tile in jee mains along with 100% marks in board exams. I also provide complete relevent study material like worksheet, practice sheet , dpps , assignment etc. Daily quizz based on assignment. Periodically test papers topic wise, minor and major as per shedule. I have helped thousands of students overcome their fear of maths.
Awesome way of teaching!! Sir is very cool and calm and teaches Mathematics with unique method. He has a huge collection of questions in his store which clarifies all doubts of a student.
