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...
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...
