Answer 3

Hmmm ok :) Let's look at the first one.

So our initial side is starting from \(\theta=0\).

With our terminal side landing on \(\theta=\huge \frac{\pi}{6}\).


We want to find another angle that is coterminal with with our terminal side.
To do so, let's add \(2\pi\) to our angle.
\[\large \frac{\pi}{6}+2\pi\]
Getting a common denominator gives us,\[\large \frac{\pi}{6}+\frac{12\pi}{6} \qquad = \qquad \frac{13\pi}{6}\]

Understand what happened there? :O
We took our angle and spun one full time around the circle, landing in the same location.

Answer 4

how did you get 12(pie) over 6?
