WebThe range is -1 ≤ cos θ ≤ +1. It has a period of 2π. The shape is the same as the sine wave but displaced a distance of π ⁄ 2 to the left on the horizontal axis. This is called a phase shift. The tan functionThe tan function is found using:It therefore follows that tan θ = 0, when sin θ = 0, and tan θ is undefined when cos θ = 0.1.
