To graph the cosine function, we mark the angle along the horizontal x axis, and for each angle, we put the cosine of that angle on the vertical y-axis. The result, as seen above, is a smooth curve that …

In these lessons, we will look at graphing the cosine function and properties of the cosine function. We will start with the unit circle. A unit circle is a circle of radius one unit with its center at the origin. The …

We will look at what the graph of the function y=cos (x) looks like by plotting values of cos (x) against the angle using the unit circle to help.

Here we will learn about cosine graphs, including how to recognise the graph of the cosine function, sketch the cosine curve and label important values, and interpret the cosine graph.
