Question

(sin 2 theta/ 1+cos 2theta)= tan theta

​

Answer 1

Answer:

Step-by-step explanation:

\frac{ \sin(2x) }{1 + \cos(2x) } = \tan(x) \\  

Taking L.H.S

\sin(2x) = 2 \sin(x) \cos(x)  

1 + \cos(2x) = 2 { \cos ^{2} (x) }

Putting in the values we get :-

\frac{2 \sin(x) \cos(x) }{2 \cos ^{2} (x) } = \tan(x)  

Hence proved....

Here let theta = x
