Period of the Cosine Function – Formulas and Examples

WebWe know y=cos (x) completes a full cycle or period for every change of 2π radians along the x-axis, and as a consequence cos (2π) = cos (0). y=cos (2x) completes a full cycle for every change of π radians along the x-axis, and when x = π, cos (2x) = cos (2 * π) = cos (0). So, for a given change in x, cos (2x) completes more cycles than cos (x). Webperiod formula for tangents & cotangents: \omega = \dfrac {\pi} {\lvert B \rvert} ω = ∣B∣π. In the sine wave graphed above, the value of the period multiplier B was 2. (Sometimes the value of B inside the function will be negative, which is why there are absolute-value bars on the denominator.) As a result, its period was 2π/2 = π.
