## Homework Statement

Write z = 1 + √3i in polar form

## Homework Equations

z = r (cos[itex]\varphi[/itex] + sin[itex]\varphi[/itex]i)

## The Attempt at a Solution

Found the modulus by

|z| = √4 = 2

Now I am stuck on this part of finding the argument:

Tan

^{-1}(√3)

now I am not sure how to go from that to the ans which is pi/3.

So would be:?

z= 2(cos(Tan

^{-1}(√3)) + sin(Tan

^{-1}(√3))i)
