That is pretty much what I thought. Thank you! I am going to just do numerical integration.

Hi, it has been a little while since I have actually had a course in this, and my math memory is terrible. I would like to find S as a function of t, when the differential relationship is the following: dS/dt= A- (B*S/(S+C))*(D-E*t) where all of the other letters are just constants. What...

Hello, I am trying to derive a formula for entropy. I have: dS= Cv/T dT + R/(V-b) dV and want to get: S= Cv*ln(T) + R*ln(V-b) + constant. Math rules seem to say i can't just integrate this up even though it looks obvious since i have two different d's on the right hand side. Maybe...

I am having trouble remembering the correct approach here. This is in regards to deriving a governing equation for conservation of momentum for a non-Newtonian fluid. I thought about posting in engineering, but it is more of a calculus question: d/dx(((-dv/dx)^(m-1))*(dv/dx)) where we are...

Thanks so much! That really clears things up.

This equation comes out of deriving the canonical partition function for some system. However, the question is more math based. I am having trouble understanding the simplification that was performed in the text: ∑ from N=0 to M of: (M!exp((M-2N)a))/(N!(M-N)!) supposedly becomes...
