Homework Help: Simple integration Q

  1. Sep 21, 2013 #1
    Calculate the are of the finite region enclosed by the curves ## y = \dfrac{2|x|}{\pi} ## and ## y = sin(x) ##

    I understand that the integral is ## sin(x) - \dfrac{2x}{\pi} ## however I'm having troubles finding where they intersect, I can only find x= 0, how do I solve ## sin(x) = \dfrac{2x}{\pi} ## ? I can see by observation that 0, pi/2, -pi/2 work but is there a method to find these instead of observation?
