Question

Value of sin2a divide by 1+cos2a

Answer 1

Answer:

Given sin 2A/1 + cos 2A.   ------ (1)

We know that sin 2 theta = 2 sin theta cos theta 

                       sin 2 A = 2 sin A cos A ------ (2).

We know that cos 2 theta = 2 cos^2 x - 1

                       cos 2 A = 2 cos^2 A - 1  --------- (3).

Substitute (2) & (3) in (1), we get

2 sin A cos A/1 + 2 cos^2A - 1

2 sin A cos A/2 cos^2 A

2 sin A cos A/ 2 * cos A * cos A

sin A/cos A

tan A.
