course provides students with a strong foundation in understanding angles, functions, and trigonometric expressions. The course begins with an introduction that outlines the course content and strategies for staying organized while learning trigonometry, ensuring a smooth and structured approach to mastering the subject.

Students then explore the six basic trigonometric functions—sine, cosine, tangent, cosecant, secant, and cotangent—learning their definitions, properties, and how they relate to right triangles and the unit circle. The course further explains how to handle trigonometric expressions for angles greater than 90 degrees, extending learners’ understanding beyond basic right triangle trigonometry.

The course includes continued exploration of the six trigonometric functions, focusing on simplifying expressions, applying identities, and understanding the relationships between functions. Practical examples and exercises are provided to reinforce learning, helping students confidently solve problems and analyze trigonometric relationships.

By the end of this course, learners will have a thorough understanding of trigonometric functions, angle measures, and expressions, equipping them for higher-level mathematics, physics, engineering, and real-
