(adsbygoogle = window.adsbygoogle || []).push({}); Derivation Trouble!!!!!

Please read the attachment with this posting: Here's the problem, I have been attempting to derive this for a couple of days now... However, it seems that whatever I do all that I end up deriving is itself again; meaning I getback to where I started. Can anyone give me a few pointers because I'm flat out of luck here. Here I use Euler's Relationships...but no help....hmm..?

e^(i*theta)-1=2i*sin(theta/2)*e^(i*(theta/2))

I have the pretty version in the attachment. :grumpy: :rofl: :grumpy:
