Volume of Revolution - The Shell Method about the y-axis

This video explains how to use the shell method to determine volume of revolution about the y-axis.

Ty for the help, but just so you know, at 4:50 you put that the equation was x^2+2 but it's actually x^2+1

thank you so much for the shell method around both the x and y axis both with functions with a square in it. made it easier for me to understand (it was getting quite confusing in my textbook)

Thank you, I annotated the error in the graph.

Thank you for the superb guide.

Now, I just need to remember it for my midterm tomorrow.

i think the graph at 5:00 is wrong, the origin should be (0, 2) not (0, 1). In fact everything on the graph needs to be shifted up one.

Awesome! Keep doing it, you math people are excellent!

Thanks, you made it so much simpler than my lecturer did haha! Cheers p.s. great quote too!

Do you ever plug in anything for the "x" or "r". Also is it crucial to distribute the "x" to the function or "y". ?

Good afternoon, sir I ask a question
* Write the limitations of disk method, cylindrical shell method and washing method to find a volume*
