i have this function
\begin{equation}
f(t) = e^t
\end{equation}

the Fourier seria have the form
\begin{equation}
f(t) = \sum C_{n} e^{int}
\end{equation}
The Attempt at a Solution
}[/B]
so i need to find the coeficients $c_{n}$ given by
\begin{equation}
\frac{1}{2\pi} \int_{-\pi}^{\pi} f(t) e^{int} dt
\end{equation}
my attempts are try to find the coeficients doing integration by parts but i don't have anithing. Any help here please.
thanks in advance
