throw the questions that give you trouble in this thread. It has been years since I have taken math courses, but I'm sure myself and others would be able to help you out. I went through calc III in school (mechanical engineer), so I should be able to help...I think...it's been a while.
Yea, I thought that too until my younger brother started asking me questions for help. lol
Calc 3/diff/etc and forgot it all as soon as I graduated.
