Determine two coterminal angles positive and negative

The video tutorial explains how to determine coterminal angles, both positive and negative. It starts by defining coterminal angles as those sharing the same initial and terminal sides. The tutorial then demonstrates how to find the smallest positive coterminal angle by subtracting 2π from the given angle. Similarly, it explains finding the smallest negative coterminal angle by further subtracting 2π. The video concludes by graphically representing these angles and confirming their coterminality.
