SUMMARY
The integral of Sin(theta)/Sin(theta/2) can be simplified by expressing Sin(theta) in terms of Sin(theta/2). Specifically, using the double angle formula, Sin(theta) can be rewritten as Sin(2*(theta/2)). By applying the identity Sin(x+y) = Sin(x)Cos(y) + Cos(x)Sin(y) with x equal to y, the integration process becomes clearer. The final integration should be evaluated from 0 to π for the complete solution.
