# Math Help - trig proofing

1. ## trig proofing

Hello,
I am currently trying to make a difficult trig proof for my maths lesson. If someone could help me make one, that would be very helpful. I have been given a left hand side, ((cosec(x))^2)\(2+cot(x)). I need it to be changed into something as different as possible from the original, with as many steps as possible, without a very long right hand side. Feel free to use all trig rules.
If someone could do this for me it would be great.
$\tan \frac{x}{2} = \frac{2\sin x}{1-\cos x}$
