MCR 3U Final Exam Review: Trigonometric Functions Prove the following identity:
15
MCR 3U Final Exam Review: Trigonometric Functions Periodic Functions: Period – Cycle – Amplitude – Equation of the Axis - The interval of the independent variable (on the x- axis, often time) needed for a repeating action to repeat one cycle. A series of events that are regularly repeated; One complete repetition of the pattern. Half the distance between the maximum and minimum values of a periodic function The equation of the horizontal line halfway between the maximum and the minimum.
