Page 1: Introduction to Trigonometric Functions
This page introduces fundamental trigonometric concepts and their mathematical representations. The content focuses on sine and cosine functions as primary trigonometric ratios, establishing the groundwork for more complex mathematical applications.
Definition: Trigonometric functions are mathematical functions that relate angles of a right triangle to ratios of the lengths of its sides.
Vocabulary: Sin sine and Cos cosine are the primary trigonometric functions used to describe relationships in right triangles and circular motion.
Example: The sine function sinθ represents the ratio of the opposite side to the hypotenuse in a right triangle, while the cosine function cosθ represents the ratio of the adjacent side to the hypotenuse.
Highlight: Understanding these basic trigonometric functions is crucial for advanced mathematical concepts and real-world applications in physics, engineering, and other scientific fields.
