What you need to know:
On top of understanding and applying the functions y = \sin x, y = \cos x, and y = \tan x, for the higher course you are also expected to be able to draw the graphs of them.
You may be asked to plot these graphs for any values of x, i.e. for any size of angle. Fortunately this is made easier by knowing that all 3 of these functions are periodic, which is to say their graphs follow a set pattern which then repeats over and over. For instance, the graphs of \sin and \cos repeat every 360 degrees, and the graph of \tan repeats every 180 degrees. On top of this, the shape of the \sin graph is exactly the same as the shape of the \cos graph, just shifted slightly to the right. Once you’ve learned the shapes of these graphs and have understood these facts, drawing the graphs is not too much trouble.
