TRIGONOMETRIC FUNCTIONS

  1.   Angles
  2.   Trigonometric Functions
  3.   Sum and Difference of Two Angles
  4.   Trigonometric Equations
  • Measurement of an angle: The measure of an angle is the amount of rotation from the initial side to the terminal side.
  • Right angle: If the rotating ray starting from its initial position to final position, describes one quarter of a circle, then we say that the measure of the angle formed is a right angle.
  • If in a circle of radius r, an arc of length l subtends an angle of  θ radians, then l = rθ
  • Radian measure =
  • Degree measure =
