Determine two coterminal angles positive and negative

The video tutorial explains how to determine two coterminal angles, one positive and one negative, for a given angle of 4π/5. It begins by defining coterminal angles and their properties, then demonstrates how to graph the angle 4π/5. The tutorial continues by calculating the smallest positive coterminal angle by adding a full revolution (10π/5) to the original angle, resulting in 14π/5. It then explains how to find the smallest negative coterminal angle by subtracting a full revolution, resulting in -6π/5. The video concludes with a summary of the process.

Explain how to convert 2π into a fraction with a denominator of 5.
