Integral of the product of a power function and an arbitrary exponentiated function

183 Views Asked by At

I was only able to find integral tables that solve

$$f(t)=\int t^c e^{kt}dt$$

but the integral I'm trying to solve has a function, not a constant, for the exponent:

$$f(t)=\int t^c e^{g(t)}dt$$

Is there a general analytic solution to this form?


The actual integral I'm trying to solve is

$$f(t)=\int t^{a-1} e^{\frac{\ln2}{\lambda}t-\frac{1}{b}t^a}dt$$

where $a$, $b$, and $\lambda$ are all constants.
