NCERT-CLASS-10-TRIGONOMETRY-SOLUTION-EXPLANATION
Simple Explanation of trigonometry for class X Overview of Trigonometry • A field of mathematics that focuses on particular angles' functions. • The sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc) are the six common functions. Before computers rendered trigonometry tables unnecessary, calculated values were tabulated for many angles. Functions are properties of the angle A, regardless of the size of the triangle. In geometric figures, unknown angles and distances can be calculated using trigonometric functions from known or measured angles. Click here to access the special offer! CosecӨ = 1/ Sin Ө Sec Ө = 1/Cos Ө Cot Ө = 1/tan Ө => So, we can see Sin Ө * Cosec Ө = 1 CosӨ * Sec Ө = 1 Tan(θ)*Cot(θ) = 1 * We will use Pythagoras' theorem multiple times to evaluate any of the missing values in the right-angled triangle. Exercise 8 Question 1 Given that in the triangle ABC, AB = 24, BC = ...
