How to Use Inverse Trigonometric Functions to Find the Angle of a Triangle

The video tutorial explains how to use inverse trigonometric functions to find missing angles in triangles. It begins with an introduction to special right triangles and the Pythagorean theorem. The tangent function is explored, demonstrating how it relates the opposite and adjacent sides of a triangle. The tutorial then covers using trigonometric ratios to solve for unknown sides and angles, emphasizing the importance of exact values over approximations. Finally, the video discusses using inverse functions, sine, and cosine to determine angles, providing a comprehensive understanding of trigonometric applications.
