Understanding the Sine Function

The video tutorial introduces the sine function, a trigonometric function derived from a right triangle. The instructor, Sua Gerwell, explains how to define the sine function using a right angle triangle, labeling the sides as opposite, adjacent, and hypotenuse. The sine of an angle, alpha, is calculated as the ratio of the opposite side to the hypotenuse. The tutorial concludes with a thank you note for the viewer's interest in math.
