(this button also refreshes the graph).

*To see two functions graphed simultaneously:*

** Enter** the second function

** Click** (to its "on" state) the check box next
to this input field.

** Click** the "Graph" button.

__Example__:*f*_{1}(*t*)=1-sin *t*,
*f*_{2}(*t*)=cos 2*t*

*Up to 5 functions can be graphed simultaneously.*
