Reversing the order of integration

    Hi,

    I want to reverse the order of this integration;

    integral(from x=0 to x=3) integral(from y=sqrt(x/3) to y=1) of e^(y^3) dy dx

    How do I change the limits of integration?

    Didn't I tell you what to do in the other thread though? Pretty sure you can move the threads you start (at least you could on the other boards I've been on) by going to Thread Tools

    Well I didn't know.
    I also don't get how to draw the pictures.

    You are told what horizontal (i.e. x goes from and to i.e. between 0 and 3) and you are told what the vertical goes from (i.e. y goes from and to i.e. sqrt(x/3) to 1)

    I get that but don't you have to change the limits of integration when you reverse the order of integration?

    Yes, you said you don't know how to draw the picture, I told you what the picture would look like. Did you draw it?
