This isn't a homework question, it's just for personal enrichment.
I've been trying to prove that [itex]\tan\frac{\theta}{2}=\frac{\sin\theta}{1+\cos\theta}[/itex]
I tried starting off with [tex]\tan\frac{\theta}{2}=\frac{\sin\frac{\theta}{2}}{\cos\frac{\theta}{2}}[/tex]
is this even the right way to start the proof? if so could someone point me the right way please? I'd really appreciate it.
