## Homework Statement

How are we able to go from the first line to the second line and then the second line to the third?

## Homework Equations

Euler Identity: e^j(theta) = cos(theta) +jsin(theta)

## The Attempt at a Solution

This problem is more about preliminary theory in my opinion so I tried understanding how they converted the problem from trigonometric functions to exponential by analyzing the Euler Identity.
