    1. The problem statement, all variables and given/known data

    This is for a solid of revolution problem, and I am trying to set these equal to eachother to find the points of intersection. How can I solve this equation??????


    2. Relevant equations

    3. The attempt at a solution

    Do you know newton's method? You'll have to resort to an iterative technique. This can't be solved algebraically.

    Yeah, I know newtons method, but really would have rather not resorted to that...LoL... anyways, I did not believe it to be solvable algebraically, but then again, I never took a trig class.

    Maybe if for very minute x value you can set sinx=x ?
