Trigonometry formulas for class 10 Trigonometry formulas for class 10 Trigonometry is the most important chapter for students whether they are studying in ICSE boards or preparing for competitions like IIT or SSC. In CBSE/ NCERT Trigonometry chapter is introduced in class 10th (Chapter 8), and in ICSE it is introduced in class 9th. Most of the time students find the chapter Trigonometry very difficult to understand and very hard to learn all the Trigonometry formulas. In this article, You’ll find all trigonometric formulas for class 10. After reading this article what will you understand:- • In this article, we will try to help students to make them understand trigonometry easily. • We will make some short tricks so that the Trigonometry formulas for class 10become easy to learn. • Also, you don’t have to Rote-learn all of them. Instead, you will develop a technique so that some of the formulas can be derived, instead of memorizing them.

This word Trigonometry basically came from combining two Greek words “trigōnon” which means “triangle” and “metron” which means “measure”.Thus, it is used to measure Triangles. In simple words, Trigonometry is a branch of Mathematics where we study relationships between side lengths and angles of triangles. Now, let me make this simpler! • QUESTION (i):- if we are given two sides of a right-angled triangle ...

In this unit, you'll explore the power and beauty of trigonometric equations and identities, which allow you to express and relate different aspects of triangles, circles, and waves. You'll learn how to use trigonometric functions, their inverses, and various identities to solve and check equations and inequalities, and to model and analyze problems involving periodic motion, sound, light, and more.

Important Questions for Class 10 Maths Chapter 8 Introduction to Trigonometry Introduction to Trigonometry Class 10 Important Questions Very Short Answer (1 Mark) Question 1. If tan θ + cot θ = 5, find the value of tan2θ + cotθ. (2012) Solution: tan θ + cot θ = 5 … [Given tan 2θ + cot 2θ + 2 tan θ cot θ = 25 … [Squaring both sides tan 2θ + cot 2θ + 2 = 25 ∴ tan 2θ + cot 2θ = 23 Question 2. If sec 2A = cosec (A – 27°) where 2A is an acute angle, find the measure of ∠A. (2012, 2017D) Solution: sec 2A = cosec (A – 27°) cosec(90° – 2A) = cosec(A – 27°) …[∵ sec θ = cosec (90° – θ) 90° – 2A = A – 27° 90° + 27° = 2A + A ⇒ 3A = 117° ∴ ∠A = \(\frac\) = 1.41, if required) (2014OD) Solution: Filed Under:

how to solve this Question :- Question :- "A circle is Drawn with a centre 'O' . 'OB' and 'PQ' are the radius of the cicle with the length of 5cm . A point 'A' is on and between (not in the mid) of the line 'PO' . A point 'C' is placed outside the circle . From point C two lines are extended in such a way that those line are joint with 'A' and 'B' respectively and form a Quadrilateral 'OACB' . 'Angle POB = 72 degree' Find angle ACB ?" I tried it for more then 30 times but i was unable to solve it , please help me to come out from this Question . now if you want to get introduced to trigonometric identities one of the best places to begin is with a right angle triangle and the moment you see this right angle triangle an equation a theorem pops into your mind doesn't it a square plus B squared equals C squared even if you try to forget this equation you'll never be able to it's that deeply ingrained in in all of us so much so we love this triangle so much that we even named the proportions like you saw on some of the previous videos if this angle is Theta we named this side the opposite side by the hypotenuse as sine theta the adjacent by hypotenuse cos theta and the opposite by adjacent side the lengths of those Dan theta now I want you to pause right now and notice that there is a difference between this equation and these equations and what is that it is that this actually says something about the world it says that the square of this site was the square of this side give...

Algebraic Identities The algebraic equations which are valid for all values of variables in them are called algebraic identities. They are also used for the factorization of polynomials. In this way, algebraic identities are used in the computation of Standard Algebraic Identities List All the standard Algebraic Identities are derived from the Binomial Theorem, which is given as: \(\begin \) Some Standard Algebraic Identities list are given below: Identity I: (a + b) 2 = a 2 + 2ab + b 2 Identity II: (a – b) 2 = a 2 – 2ab + b 2 Identity III: a 2 – b 2= (a + b)(a – b) Identity IV: (x + a)(x + b) = x 2 + (a + b) x + ab Identity V: (a + b + c) 2 = a 2 + b 2 + c 2 + 2ab + 2bc + 2ca Identity VI: (a + b) 3 = a 3 + b 3 + 3ab (a + b) Identity VII:(a – b) 3 = a 3 – b 3 – 3ab (a – b) Identity VIII: a 3 + b 3 + c 3 – 3abc = (a + b + c)(a 2 + b 2 + c 2 – ab – bc – ca) Solved Examples of Algebraic Identities Example 1: Find the product of (x + 1)(x + 1) using standard algebraic identities. Solution: (x + 1)(x + 1) can be written as (x + 1) 2. Thus, it is of the form Identity I where a = x and b = 1. So we have, (x + 1) 2 = (x) 2 + 2(x)(1) + (1) 2 = x 2 + 2x + 1 Example 2: Factorise (x 4 – 1) using standard algebraic identities. Solution: (x 4 – 1) is of the form Identity III where a = x 2 and b = 1. So we have, (x 4 – 1) = ((x 2) 2– 1 2) = (x 2 + 1)(x 2 – 1) The factor (x 2 – 1) can be further factorised using the same Identity III wh...
