relating to the study and application of angles and their related functions
- Trigonometric identities express relationships between trigonometric functions such as sine, cosine, and tangent.
- Trigonometric ratios like sine, cosine, and tangent are used to solve problems involving right triangles.
- The unit circle is a fundamental concept in trigonometry, used to define trigonometric functions for all angles.
- Trigonometric functions are periodic, meaning they repeat their values at regular intervals.
- Trigonometric graphs illustrate the behavior of trigonometric functions over a specified range of angles.
