Introduction to Trigonometry Functions in Right-Angle Triangles

The video introduces trigonometry, focusing on right angle triangles and the three main trigonometric functions: sine, cosine, and tangent. It explains how to identify the hypotenuse, opposite, and adjacent sides based on the angle's position. The sine function is used with the opposite and hypotenuse, the cosine function with the adjacent and hypotenuse, and the tangent function with the opposite and adjacent. The video also covers using inverse functions to find angles and emphasizes memorizing trigonometric tables.

Describe the sine function and its application in trigonometry.

What is the relationship defined by the tangent function in a right triangle?
