Question

How do you determine the quadrant in which `pi/5` lies?

Answer 1

Q1

Explanation:

I would convert to degrees. That helps me a lot more.

We can use the conversion factor `180/pi`.

`pi/5 = pi/5 * 180/pi = 36˚`

This is clearly in the first quadrant, because `0 < 36 < 90`.

Hopefully this helps!
