Evaluate the difference for two angles for sine from a triangle

The video tutorial covers finding the sine of angles alpha and beta, discussing the constraints of angles, and creating triangles to solve trigonometric problems. It explains the use of the unit circle and the Pythagorean theorem to calculate sines and cosines. The tutorial concludes with final calculations and simplification of results, emphasizing the use of formulas and understanding of trigonometric concepts.

Describe the process of using the Pythagorean theorem to find the hypotenuse in the context of this problem.

How does the use of triangles differ from using the unit circle in evaluating sine and cosine?
