Cosine: Introduction to the Cosine Function - Wolfram

WebThe cosine function is a periodic function which is very important in trigonometry. The simplest way to understand the cosine function is to use the unit circle. For a given angle measure , draw a unit circle on the coordinate plane and draw the angle centered at the origin, with one side as the positive -axis. WebWrite the equation of the function f of x graphed below. And so we have this clearly periodic function.
