Hi,

I have my math exam in a few days and that's the last question I have to solve to complete the trig part.

$\displaystyle 2sin x(1+cos x) = \frac {2sin^3 x} {1-cos x} $

I've been trying to use sin^2x + cos^2x for LS and RS however I'm getting nowhere with that, mainly because of the right side fraction.

Any help appreciated.

Thank you very much!
