Thus, we see that both these functions could be expressed as sums of sines and cosines. It is possible to show that every product of trignometric functions can be expressed as a sum of sines and cosines:
$$
-\begin{arary}{ccl}
+\begin{array}{ccl}
e^{i\theta} & = & \cos \theta + i \sin \theta\\
\end{array}
$$
