Homework Help: Area between two curves, trig help.

  1. Sep 29, 2012 #1
    1. The problem statement, all variables and given/known data

    I would appreciate it if someone could give me a detailed description on how to find where the two graphs intersect. I was able to figure out that they intersect at -/+ pi/3 but that was pure guess work using my calculator and plugging in random values. I can solve these problems on my own but just need someone to guide me on how to find the x values of these trig monsters! [see below for problem and attempt]

    3. The attempt at a solution

    Successfully solved the problem, but still would like to learn how to find the x values algebraically instead of doing guess work.
