Question

what are the three identities of trigonometry​

Answer 1

Answer:

The three main functions in trigonometry are Sine, Cosine and Tangent. That is our first Trigonometric Identity.

Cosine Function: cos(θ) = Adjacent / Hypotenuse

Sine Function: sin(θ) = Opposite / Hypotenuse

Tangent Function: tan(θ) = Opposite / Adjacent

Answer 2

There are three identities when it comes to solving trigonometric equations.

sin^2theta + cos^2theta = 1

cosec^2theta - cot^2theta = 1

tan^2theta - sec^2theta = 1

Hope this helps you!
