Example about the y-axis.

Thank you! All of your videos are very helpful, I'm confused about how to apply the formula when the curve is rotated about "y=2" or about "y=r"

No one here knows how to math. You did fine.

Your the best. Thank you for clearing things up for me.

Helpful, but too fast through the math. The derivation discussion last video was excellent.

Hi, how did you come up from y=x^1/3 to y^3=x ?

Dear Mr Mathis power 4u Find the surface area due to the rotation of the area between f(x)=x^2and g(x)=x

Surface of revolution of parabola y^2=4ax on revolution about x=0,
from x=0 to x=a

[MareamalQadhi]

When you solved for x it should be y^1/3
