worth starting by having a look at the definition/properties of complex exponentials

Do you know what the definitions of Cartesian, Polar, and Exponential forms are?

You may need the following equations:

[tex]\begin{array}{c}x=r\cos \theta \\

y=r \sin \theta \\

x^2 + y^2 = r^2 \\

\tan \theta = \frac{y}{x}\\

e^{i \theta} = \cos \theta + i \sin \theta

\end{array}[/tex]

y=r \sin \theta \\

x^2 + y^2 = r^2 \\

\tan \theta = \frac{y}{x}\\

e^{i \theta} = \cos \theta + i \sin \theta

\end{array}[/tex]
