    Determine the order of integration and then evaluate the integral

    \int_{0}^{4}\int_{x}^{4}\frac{sin(y)}{y}dydx

    How do you go about doing problems like this? Thanks.

    Reverse the order of integration. To get the new integral terminals, I suggest you draw appropriate graphs and shade the region of integration.
