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.
Thanks in advance,
James

Tell you class to show that,
$\displaystyle \tan \frac{x}{2} = \frac{2\sin x}{1\cos x}$
