Determine two coterminal angles positive and negative

The video tutorial explains coterminal angles, focusing on initial and terminal sides. It covers angle measurement, breaking angles into fractions, and estimating positions. The tutorial demonstrates methods to find coterminal angles using 2π, both in positive and negative directions. It also explains subtracting angles and the importance of having a common denominator when dealing with fractions.

Describe how to determine the negative direction of an angle and its implications.

What is the relationship between the angle -2π/15 and the fraction 30/15?
