Question

prove all the fundamental trigonometrical identities all​

Answer 1

Proving Trigonometric Identities - Basic

\sin^2 \theta + \cos^2 \theta = 1. sin2θ+cos2θ=1. In order to prove trigonometric identities, we generally use other known identities such as Pythagorean identities. Prove that ( 1 − sin ⁡ x ) ( 1 + csc ⁡ x ) = cos ⁡ x cot ⁡ x .
