Question

sinx/1-cosx+sinx/1+cosx=2cscx

Answer 1

What are you supposed to do with that?

Answer 2

Prove it

Answer 3

\[\frac{\sin x}{1-\cos x}+\frac{\sin x}{1+\cos x}=2\csc x\]

Answer 4

\[\frac{\sin x(1+\cos x)}{(1-\cos x)(1+\cos x)}+\frac{\sin x(1-\cos x)}{(1+\cos x)(1-\cos x)}\]

Answer 5

\[\frac{\sin x(1+\cos x)}{1-\cos ^2x}+\frac{\sin x(1-\cos x)}{1-\cos ^2x}\]

Answer 6

\[\frac{\sin x(1+\cos x)}{\sin ^2x}+\frac{\sin x(1-\cos x)}{\sin ^2x}\]

Answer 7

\[\frac{1+\cos x}{\sin x}+\frac{1-\cos x}{\sin x}=\frac{2}{\sin x}=2\csc x\]
