Hey guys! Having trouble with this question.. It's a proof so you have to pick one side and work with it until it equals the other side. I can't seem to get it...

Cotangent X(Cotangent X + Sine X) = Cosecant^2 X

I got the left hand side down to..

[Cosine^2 X + (Cosine X Sine^2 X)] / Sine^2 X

or using my identities..

[(1-Sine^2 X) + (Cosine X Sine^2 X)] / Sine^2 X

I'm stuck there and I don't know what to do.. Did I make a mistake or am I just blind and can't go any further? Need help!
 
Nevermind. I misread the question. It's actually..

Cotangent X (Cotangent X + Tangent X) = Cosecant X

I don't know why I put Sine where Tangent was supposed to be...
