    I understand the graph. I want to see the integration.

    Why isn't the integral of 2a, 2ax?

    it is, but I plugged in the boundaries -2a and 2a immediately

    How is (2x)^3= 16a^3

    Rather (2a)^3=16a^3

    we think exactly the same I just prefer to plug in the boundaries right away.Also this is also useful thing that you can use when you try to solve the integral of an even function:

    I could use this property in the example above, I would get the same result :D

    ok, if you have some troubles with integrals be free to post so we can solve it fast and easy....well, I gotta go now, it's 2:23 in my country...good night :D
