Area of a Surface of Revolution Calculus 1

In this lesson I explain the relationship between the lateral area of a right circular cone allows us to find the Area of a Surface of Revolution.
Rule for Area of a Surface of Revolution at 16:37 ,
Example with a horizontal axis of rotation at 19:11 NOTE: at 19:44 I should say "2PI times the definite integral from a to b..."
Example with a vertical axis of rotation at 28:02 ,
Example finishing with numerical integration with a calculator 33:57

You are a true hero, I wish that my teacher teaches like you. I promise to tell all of my friends about you. Tanks for saving my life.

Thank you Mr.Tarrou!! It looks like our journey of calculus lessons will soon be coming to an end

revolve area between y=8x, y=x, 0 to 1, about x=15 want to find the surface area of ​​this rotation. It is very necessary, Prof RobBob

Wow, mind blowing! Thanks for all of your videos! You're the BEST math teacher I have ever seen. (better than all of my teachers) Thanks for making these great tutorials and guess what? you have earned a new subscriber :)

Very nice video. Cleared many concepts.Too good. Just one thing- when switching boards in between the video u r using kind of slide show right Prof? Also like how u added the starting title. Its all sort of slideshow right?This looks so good so wanted to know.

Sir I recently saw your video and became a big fan instantly. Your knowledge is just immense. Just a small correction in this video - at 19:44 you by mistake said 2PIR(in place of 2PI) and then a &b ( in place of definite integration of a to b). Just telling as I wanted my sir's videos to be perfect..:)..I know you did not realize this while speaking right?

33:09 may i ask why you didnt change the bounds because you used u-sub?

[shiinaoneesama]

When will I learn this? I just finished Calc 1.

[colinmartin]

Beautiful boardwork but this is absolute gibberish to a calc 2 student.
