Hey, I need to integrate this and I am having troubles with it, here it is

$$\int e^((2*pi*j*f*t)-((f^2)/k))) df$$

the integral is with respect to f, you can take j,t and k as normal numbers as they will be constant. Thanks for the help.

Do you mean $$\int e^{2\pi jft} - \frac{f^2}{k} df$$?

If so, do you know how to integrate $$\int e^{kx} \ dx$$ where k is a constant? As well as the power rule for integrals?
