1. The problem statement, all variables and given/known data Evaluate the integral 4cos(x^2)/ (2((z)^(1/2))) dxdydz, limits for x 2y to 2, for y, 0 to 1 and for z 01, by changing the order of integration. 2. Relevant equations Would I need to change the limits in order to accurately change the order of the integration? Im thinking not, I could just switch the dx and dy and Integrate. I guess thats what she is asking. 3. The attempt at a solution My problem? I am having a heck of a time integrating this function. Please help me with getting started on integrating it.
