Hi
Can someone please help me on the following question
Write w=e^1+3i in Cartesian form.
thanks
It's not because there are exponentials that it is still in polar form.
In cartesian form, it would be like $\displaystyle a+ib$, where a and b are real numbers.
But $\displaystyle e^x$ is a real number, for any real x.
So $\displaystyle e^x \cos(y)$ is real and $\displaystyle e^x \sin(y)$ is real.
The formula Plato gave is, without any doubt, a cartesian form, the one corresponding to $\displaystyle e^{x+iy}$.
