Hi Quoc.. your videos are PERFECT... I keep saying that in other videos that you have made. You keep it simple and SO CLEAR!! You are a Genius in your ability to present Calculus videos. You're going to go places with your Intuition and Talent for Teaching. Thank you!
Haha thank you! I'll show you how to find the volume of other shapes like the cone. You'll likely get that question on the exam ~ here's the link to all of my Calculus II videos: th-cam.com/play/PLeTO6OT3-FKmuCeO97iKt_Aibx-a938JA.html

That's because r is a constant and x is a variable :) In the integral, notice it's dx at the end right? So the integration rules are only for x. I can rename r to something else like c and you know that c is a constant so you can't apply the integration rule. Let me know if that makes sense!
You could do it if you'd like, but I do not recommend it as it will not work with other shapes that are not symmetrical. On exams it's best to use the general approaches, and negative numbers aren't that bad to deal with. Let me know if it makes sense.

That's very kind of you! I just posted two more videos on work problems! Are there any kinds of topics you think I should do next?
Thanks a bunch!
No worries!
Best teacher on this topic.

Excellent.
Thanks for listening
Very well explained.
Glad it was helpful!
Ty!
:)
Thank you sir 🙏 love from india ❤

Keep up the good work!
Thanks, will do!
Hey Quoc, how come at 3:30 the integration of r^2 isn't r^3/3 based on integration rules
That's because r is a constant and x is a variable :) In the integral, notice it's dx at the end right? So the integration rules are only for x. I can rename r to something else like c and you know that c is a constant so you can't apply the integration rule. Let me know if that makes sense!
Bro you are definitely a very great mind

Great. So no need for using axes x, y and z.?
For this one, no :)
why not just calculate for a hemisphere and double it?
prevents dealing with negative quantities
You could do it if you'd like, but I do not recommend it as it will not work with other shapes that are not symmetrical. On exams it's best to use the general approaches, and negative numbers aren't that bad to deal with. Let me know if it makes sense.
