Question

if sin theta =cos theta ,find the value of theta​

Answer 1

Step-by-step explanation:

let theta = A

sin A = cos A

sin A/cos A = 1

tan A = 1

tan A = tan 45°

A = 45°

So, theta = A = 45°

Answer 2

Sin theta = cos theta

sin theta / cos theta = 1

tan theta = 1

tan theta = tan 45°

theta = 45°
