The video tutorial covers coterminal angles in both degrees and radians, using the unit circle and reference angles to find exact values of trigonometric functions. It explains right triangle trigonometry, including special triangles, and how to identify quadrants based on the signs of trigonometric functions. The tutorial also introduces the hand trick for determining coordinates on the unit circle.
