Question

consider the complex number z=-3+4i
a) graph z in the complex plane
b) write the complex number in polar form with argument theta between 0 and 2pi
c) use de moivre's theorem to find z^3 in polar form

Answer 1

hey lebrick, you have some tough questions. what course are you taking?

Answer 2

college trig

Answer 3

To plot in the complex plane:
the complex number has a real part and an imaginary part.
Use the real part as the x coordinate and the imaginary part as the y coordinate.

Here's an example:
z = 2 + 5i
