    double integral- reverse the order

    reverse the order of integration.

    integral from 0 to 1 of the integral from 1 to e^y of f(x,y) dx dy


    i don't understand how to do this since there isn't a function, it's just f(x,y)?

    You create the region from the integration bounds.

    Once you draw the region, you can easily switch the integration bounds...

    i'm sorry i'm still kind of confused i've never done this before and the book doesn't have any examples. i googled it but that only confused me more
    i've drawn x=0, x=1, and 1=y. is e^y the same as e^x or is it rotated?
