# Find Fourier series $f(t) = e^{jx t}$ , $−\pi < t < \pi$ [closed]

I need to find the Fourier series of the $$f(t) = e^{jxt}$$ , $$− \pi < t < \pi$$ What will be the first step to solve it?

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.

There is no need for you to find Fourier series just compare with equation $x(t)=\sum_{-\infty}^{+\infty}C_n*e^{j*w_n*t}$ we will know $C_n,w_n.$
