| Hi I have been assigned by my professor an assignment but I cannot figure out how to use Dsolve and matripexp correctly to solve the problem. I understand the problems and know that its a third ODE but I just don't have much experience with... |

| Hi Iam trying to use Nintegrate but I keep getting an error. Can somone explain how I can use it correctly. THanks.[mcode]Clear ["global'*"] Nc = 2.8*10^19; nexact [\[Eta]c_] := NIntegrate[ Nc*(2/\[Sqrt]\[Pi])*(x^(1/2))/(1 + e^(x - \[Eta]c)), {x,... |
