Me bro an I are doing his homeowrk (yes, its 10:30, this is early for us). given a huge diagram me and my bro finaly managed to derive the correct equation :
Theta/sin(Theta) = (1001*180)/(1000*PI) to be solved for theta. Weve done it by iteration, but would prefer the exact solution. Does anyone here have a clue how to get it?

Barry. Iteration in this case is simple. You just play around with values of theta until the result of the LHS is close to the constant RHS. Except 4.44 gives answers close to a threshold later in the question, so i wanted a more accurate answer.
Besides, the brat hasnt been taught iteration yet and im not supposed to be helping.

I've forgot most of it, (except the new stuff that I am doing at A-level), but even I can remember differentiation!!! Iteration I cannot however!
