# Graph of cos(x)

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

What is the maximum value of cos(x)?
What is the minumum value of cos(x)?
What do you think would happen if we continued the graph beyond an angle of 2pi radians?
What do you think would happen if we had negative angles?
