Why matlab does not integrate?

why matlab don't integrate for my code?

Hi,

Your function is too much complex that int is unable to compute a closed form of indefinate integral. Numerical Integration will be more suitable for this function, but for that you will be evaluating definate integral.

If int cannot compute a closed form of an indefinite integral, try to approximate the expression around some point using taylor, and then compute the integral. For example, approximate the expression around t = 0. (Approximate Indefinite Integrals: https://www.mathworks.com/help/symbolic/int.html)

fApprox = taylor(f2, t, 'ExpansionPoint', 0, 'Order', 10);
int(fApprox,t)

Kindly check if you got some help from this.
