    My new U substitution approach? is this legal?

    I don't believe that would work. I mean you couldn't really take a second indefinite integral because you must add a constant when integrating.

    Expand and simplify this formula

    Just to add on a tid bit, Please Excuse My Dear Aunt Sally is a little bit better--Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

    Expand and simplify this formula

    kind of, just remember you don't multiply by something you're adding i.e. 3a+a(6-2a)=9a-2a^2 NOT 18a^2-6a^3 do you follow?

    Double integral, polar coordinates

    I wouldn't do this in polar, though the x^2+y^2 makes it tempting... Draw out the triangle and figure out the equations for the lines that make it up, use these lines as your bounds for your double integral.

    Finding the Volume using a triple integral

    Got it! Now I just need to evaluate which shouldn't be a problem, thanks so much!

    Finding the Volume using a triple integral

    I drew it in the xy plane and am looking at it in grapher, I understand the y bounds now, but x and z are still confusing, should x be -3<x<3? I have absolutely no idea how to go about solving for z...

    Finding the Volume using a triple integral

    Homework Statement Find the volume of the solid bounded by the cylinder x^2+y^2=9 and the planes y+z=5 and z=1Homework Equations NoneThe Attempt at a Solution My main problem is setting up the integral. So far what I have is 1 as the integrand, my order of integration is dydxdz and my bounds...
