A nice example function to display is f:R->R; x |-> f(x) := cos(2x)*x. In order to display this function, do the following:

1. type its function term

   cos[2*x] * x

   and confirm with Enter.
2. Then you should see the graph of f.

Another nice example function to display is g:R->R; x |-> g(x) := 1 / cos(1/x*4). In order to display this function, do the following

1. type its function term

   1 / cos[1/x * 4]

   and confirm with Enter.
2. Then you should see the graph of g (and f).
3. To adjust which part of the graph is shown, either use the arrow buttons, or double-click on the panel and change the range settings, directly. Good settings for f(x) is the range from -10 to 10 for both, x and y values.

Another nice example is sin[2/x]*x.
