As soon as you start typing
a new equation, a check mark will automatically appear in the
corresponding selection box. If you want to prevent an equation
from being graphed, then simply uncheck the selection box.
For multiplication, you can
omit the multiplication sign (*). For example instead of 2*x you
can simply type 2x. Other examples include 2(x), 2(x+y) and 2xy.

editor will automatically fill-in the rest. The following table summarized
the functions that are supported:
