Trigonometric Functions

Chapter Overview

This chapter expands the basic concepts of trigonometry to a broader set of angles using radian and degree measures. It introduces trigonometric functions as periodic functions and explores their properties, graphs, and identities. These concepts are foundational for calculus, wave analysis, and coordinate geometry.

Important Keywords

  • Radian: A measure of angle based on the radius of a circle.
  • Trigonometric Functions: Functions of an angle like sin(x), cos(x), tan(x), etc.
  • Periodicity: The repeating nature of trigonometric functions.
  • Principal Value: The unique value of an inverse trigonometric function in its restricted domain.
  • Identities: Equations true for all values within the domain (e.g., sin²x + cos²x = 1).
