Below, I have solved all of the problems and their parts, hope this helps!

For Problem 1:
a) Arc Length approx. = 6.847
b) Surface Area approx. = 125.870
c) Surface Area approx. = 207.625

Problem 2:
a) Arc Length approx. = 9.294
b) Surface Area approx. = 116.786
c) Surface Area approx. = 127.121

Problem 3:
a) Arc Length approx. = 5.254
b) Surface Area approx. = 70.721
c) Surface Area approx. = 124.752

Watched this video 4 hrs before exam. Good enuf

I like that you simplified the vector sum of the differentials by factoring out 1/dx², but can you make a video one day proving that derivatives in Leibniz notation can be treated as fractions?

This man singlehandedly saved my grade in calculus 2 he is very good :) and smart :)

So if we are not allowed to use the calculator, how would you do the integral for the arc length question

[anthonytam]

Arc Length is equal to ln(7/3)+6 (approx: 6.847)!

This will be more amazing if the function is rotated about the line ax+by+c=0.

this video is unlisted but i still get the notification

[sushiiann]

where can i get the final answer for each question here?

[alialden]

Got finals in 2 days. I'll let you know how I did on these.
