Determine two coterminal angles for 900 degrees

The video tutorial explains coterminal angles, emphasizing that there are infinitely many such angles. It describes the concepts of initial and terminal sides of an angle and demonstrates how to find coterminal angles by adding or subtracting 360 degrees. The tutorial focuses on finding the smallest positive and negative coterminal angles, using examples to illustrate the process. The key takeaway is understanding the method to calculate coterminal angles and recognizing the infinite possibilities of such angles.
