( frac{cos x+1}{sin ^{3} x}=frac{csc x}{1-cos x} )

Question

Accepted Answer

Step:1 ：( frac{cos x + 1}{sin^3 x} = frac{1}{sin x (1 - cos x)} )Step:2 ：( (cos x + 1)(1 - cos x) = sin x )Step:3 ：( sin^2 x = sin x (1 - cos x) )

Answer

Step: 1 ：( frac{cos x + 1}{sin^3 x} = frac{1}{sin x (1 - cos x)} )Step: 2 ：( (cos x + 1)(1 - cos x) = sin x )Step: 3 ：( sin^2 x = sin x (1 - cos x) )

\( \frac{\cos x+1}{\sin ^{3} x}=\frac{\csc x}{1-\cos x} \)
