Gah, Wrong part of forum to post this. I apologize, please move if some one has the power (=

Hello! This is a question purposed to me by my professor as we went over the mathematics behind the diffusion of heat flow through solids. Many parts of this question are left up to us to create. Here is what i am working with. ***** A m^3 box made of Brick .1m thick has air at 30C...

Thats a good point halls of ivy... some how i manage to combine the spherical and change it to cos instead of sin. Let me attempt it with that change!

So it's been a couple days so far, and I've still not been able to change the cords of this problem to spherical or cylindrical and reproduce my answer of pi/2... Can some one look at my bounds for when i tried to change to Cylindrical Cords? Original problem restated----Volume bounded by z=...

Just getting frustrated on this problem now... i feel that I've lost understanding on how to set up the limits let alone understand how the integral is going to work. Any help would be amazing

Thanks for fast response pingpong. Ok, so how did you figure his answer was correct? Were you able to use an integral table? cause i would really like to know that process... i have no clue on how to do V= Int(0->2) [4/3 (2y-y^2)^(3/2) dy]= Pi/2 . without a computer's help that is. I'm still...

I would solve this using Mathematica on my computer, but for some reason it rolled back my registration and i can't access it. I would like to have some work done for this by tomorrow, and i know that my professor does not like when we "cheat" using a computer to do integrals anyways hahaha.

Homework Statement Volume enclosed by: z= x^2 + y^2 and z= 2y. This should look like 1/2 of a bowl only on the +y side of the x y z plane I believe. I want to know if integrating in different order or cord system will affect the result. I am having a lot of problems attempting...
