how to get integral of (u^4*exp(u)/(exp(u)-1)^2) du with limit 0 to T (where T is temperature) in MATLAB. I want analytic solution in T where T value will be assigned later. I tried the following: >> u=sym('u')
>> int((u^4*exp(u)/(exp(u)-1)^2)) Warning: Explicit integral could not be found.
int((u^4*exp(u))/(exp(u) - 1)^2, u)
