    cos^3(t) = (1-sin^2(t)) cos(t)/5

    when you integrate you get sin(t)/5 -sin^3(t)/15

    all of that evaluated with respect to 0 is just 0 right as sin(2pi) is 0...

    I also get 84 pi --- send the answer

    The only thing I can think of is that they also compute the flux through

    the base of the solid in the x-z plane as well

    if that's so then what's the answer?

    This thread is getting way out of hand.

    If you're calculating flux integrals then there is certain assumed background knowledge that you are expected to know. This thread is not the place to be revising that knowledge.

    You have been given sufficient information to attempt this queston. There comes a point where you have to go ahead and calculate your answer without getting confirmation that every step is correct.

    Thread closed.
