This is a nice one.
I love a simplified too which builds on the surface of sphere:
Int 4 pi r^2 dr | 0 to r = 4/3 pi r^3

You need to prove the area of a disc first.

It’s been a great series so far!

Limit your carb intake,sleep well,exercise occasionally and you'll make that 1000 before you know it..I enjoy these as refreshers for I was a student of The calculus in the late 1970s.

10% done! ✅️ crazy to say that after number 100! Congrats, keep it up! ?
2026-08-15 19:43
Congrats, 10%!
2026-08-15 19:38
Hehe you can see the rehersal on the whiteboard when you start. Congrats on reaching 100!

DAY 100 LETS GOOOO!!! I Love these vids so much thank you for these
2026-08-15 18:37
Day100?
2026-08-15 17:53
I was feeling a bit emotional about 10% even before you said it! ?
2026-08-15 16:58
Day 100
2026-08-15 16:41
Welp, we have until 1/31/2029
2026-08-15 16:31
lez go!!
10% closer
2026-08-15 16:21
Day 100 ???
10% Done ?
2026-08-15 16:19
congrats on 100 days
2026-08-15 16:18
these are fun to binge watch
2026-07-25 20:45
Even though I don't understand almost anything, I still enjoy watching it lol. I'm starting Calc 2 next week btw.
2026-08-16 08:12
Why is it an even funtion?
2026-08-16 06:10
Do something special when you reach day 271 and 314
2026-08-16 02:35
Yes 100 days absolutely flew by, it feels like we're almost in the end. But I'm sure that random numbers like 168, 271, 314, 693 and everything in-between is going to feel infinite. And that's perfect. You should start a 10000 days series after this 1000 days series ends. That'd be fun to watch
2026-08-15 23:58
Congratulations on the first 100 videos! I'm not sure how far ahead you are recording these, but a reminder that, for #314, it might be cool to make the answer = pi (if you think that's a good idea)
2026-08-15 23:33
Woo hoo - 10%! ?
2026-08-15 21:38
I see what have been erased from the board ..
2026-08-15 21:29
The most transcendental decision in these problems is just to put the correct names and letters on everything. Not an easy task though...
2026-08-16 14:08
I was bored one day and found a different method for finding its volume! All you do is integrate the surface area of the sphere made at each point along the radius of the sphere:
int(0,r)(4 pi R^2 dR) = 4pi (R^3)/3 (0,r) = 4pi/3 (r^3-0^3) = 4pi/3 r^3
2026-08-16 13:42
You’re 10% there! ? ?
2026-08-17 08:55
Bro I am beginner in calc, i think r must be related by x by something like integral chain rule while u treated r as constant and wrote r²x while integrating, pls explain, your response will certainly help a person and will be appreciated , and I have oned notifications for that
2026-08-17 23:47
100!!!
