Unit 15: Introduction to Trigonometry
Trigonometry explores the relationships between angles and side lengths in triangles, especially right triangles. This unit introduces the unit circle, basic trigonometric functions, graphing, and fundamental identities, which are foundational for geometry, calculus, physics, and engineering.
Unit Goals
- Understand angles measured in degrees and radians.
- Use the unit circle to define sine, cosine, and tangent functions.
- Graph sine, cosine, and tangent functions and identify key features.
- Learn and apply basic trigonometric identities (Pythagorean, reciprocal, quotient).
- Solve simple trigonometric equations.
- Interpret trigonometric functions in real-world contexts such as waves and rotations.
