Literally the only video I could find that doesn’t just ramble on about the concept of 3D objects thank you, your a life saver

YOU ARE SUCH A GOOD TEACHER! You helped me understand the radius when no one else could and you did it in like 2 minutes. Thank you so much. Sending love 4 years later.

I really struggle with revolution, but I have never seen such an amazing explanation on YouTube. Thank you so much :D

[jamiehendrickx]

I'm a math tutor and needed to review this material. From one math teacher to another, you have a gift!! Thank you for making this so simple to understand.

Visualizing how to find the big R and little r was SO USEFUL!! THANKS!!

[rapidsfire]

Thank you for making this video! Ive never been someone who math just clicks for so the thoroughness of your lesson is a godsend. Thank you!

Explaining in a way humans can understand. Not a rambling psychopath. Thank you

[domanirobledo]

This was so helpful, your explanations even helped me figure out how to find the volume of areas between two curves revolved around given lines. You’re a rockstar.

Ms. Callahan, thank you very much for the help and explanation. I was able to get ahead of my class using your video!

I love that you explain every single step clearly, and never take anything for granted. You have an art for teaching.

Great video and straight to the point, this was immensely helpful. Thank you!

I usually don't leave reviews but man, this answered all the questions I had about when adding the line of revolution or when subtracting! thank you.

Your explanation of how to find the function that describes the radius when rotated around a non 0 axis was so simple and intuitive that now I'm embarrassed I had to ask. Unfortunately, I can't find the function that describes the volume of my gratitude so I'll go with one of the basic you.

thanks so much...i finally grasped the concept of volume of solid revolting on axes different from x or y

[shumokhalmutairi]

Thank you so much. Very excellent explanation, after watching the video, the solution seemed much easier for me. I thought that drawing was very difficult, and now I have become very skilled.

THANK YOU SO MUCH!!! I have been struggling to understand how to set up the integral but this video explains it so well!!!!

This is the best explanation of this topic I've seen. Thanks a lot

[stealthworx]

Lady you are a legend this was about as easy to understand as this topic could possibly be explained.

[swagatdas]

At 1st I have huge doubt about this but now its crystal clear 😍thank u so much

[Kaka-soda]

Thank you so much! Make me understand how this works
