I am trying to solve this integral. My first step was to try and see what the integral looks like after integration using symbolic integration. but i cant seem to get it correctly.
here is my code:
syms eps betta delta
f(eps,betta,delta) = (tanh(0.5*betta*sqrt(eps^2 + delta^2)))/sqrt(eps^2 + delta^2);
F = int(f,eps);
The output is just :
F(eps, betta, delta) =
int(tanh((betta*(delta^2 + eps^2)^(1/2))/2)/(delta^2 + eps^2)^(1/2), eps)
The output seems to be the same as my input. I was wondering if it is becasue this equation needs to be solve numerically. Greatly appreciated if anyone can help. Thank you very much.
