EZ Graph - Cosine Function, -360 to 360 degrees

Click the 'Draw graph' button in the lower left corner of the EZ Graph app. Explanation below.

Here is the conventional notation for this cosine function and the computer language type of notation used with EZ Graph:

 

f1(x) = cos(x) translates to EZ Graph as f1(x) = cos(x)

 

The two notations are the same for this example.
