Graph the complex number and express it in rectangular form:

10(cos6 + i sin6)

I'm confused because it doesn’t specify whether 6 is an angle or not.

i as in the imaginary number!!

I suspect the 6 should be $$\theta$$, in which case we have: $$f(\theta)=10(\cos\theta+i\sin\theta)$$

This is already in rectangular form!  In polar form it is: $$f(\theta)=10e^{i\theta}$$
