Find the values of `theta` which satisfy `r sin theta=3` and `r=4 (1 + sin theta), 0 <= theta <= 2 pi`

Explanation

To solve the equations \( r \sin \theta = 3 \) and \( r = 4(1 + \sin \theta) \), we will eliminate \( r \) and find the values of \( \theta \) that satisfy both equations within the interval \( 0 \leq \theta \leq 2\pi \).

### Step 1: Substitute \( r \) from the second equation into the first equation
We have:
\[ r = 4(1 + \sin \theta) \]
Substituting this into the first equation:
