What is the tangent function

The video tutorial introduces the concept of right triangles, emphasizing the necessity of having a right triangle to define the hypotenuse. It then explains the tangent ratio, commonly referred to as 'tan', which is the ratio of the opposite side to the adjacent side in a right triangle. The tutorial provides a detailed explanation of how to apply this ratio to find the tangent of an angle, even when the angle is unknown. The focus is on understanding the relationship between the sides of a right triangle and how this relationship is used in trigonometry.
