  • Shell method for the volume of revolution. We will cover 7 calculus 1 homework problems on using the shell method to find the volume of the solid of revolution from the Stewart Calculus textbook book. This calculus tutorial will help you if you are taking calculus 1 or ap calculus AB.
    Hint, it's easier to use the shell method than the disc/washer method when we are given y=f(x) and we rotate about the y-axis or a vertical line.
    If you need to learn the disc/washer method, please see this video 👉 • Disc and washer method...
    0:00 y=x(x-1)^2, rotated about y-axis
    3:24 y=sin(x^2), rotated about y-axis
    6:04 y=cbrt(x), rotated about y-axis
    9:23 y=x^(3/2), rotated about x-axis
    13:20 y=4x-x^2, rotated about x=1
    19:43 x=2y^2, rotated about y=2
    25:54 y=tan(x), rotated about x=pi/4

    crazy that cylindrical cells aren't part of the AP Calc curriculum. They expect you to find the inverse function and revolve that using washer integration instead.

    how would you solve using the shell method when one y value is your equation, another y value is a whole number, and your x value is 0 (about the y axis)?
    very similar to the problem you solved at 9:33 but about the y axis.

    • @pronoobbs1323
      @pronoobbs1323 Před 8 měsíci +1

      you would use the disk method so x = (3sqrt(y))^2 and the limits of integration would be from 0 to 8 and you would use the formula pi * r^2

    at 14:31, why were you just able to move the 3 over to the other side, instead of subtracting it on both sides? is because the equation equates to 0, and I just didn't know that you can do that?

    For the 4th example, why do you not do it in terms of x? I was watching Organic Chem Tutor and he said that when it comes to rotating against the x-axis, your terms should always be in terms of x? But I've noticed it is not done here, and Khan academy doesn't do it either.
    Can someone please clarify?
