The

button checks whether the generated solution is correct. You are

probably not going to use this button very often because, when necessary, the
software incorporates the checking into the solution process (i.e. when solving a
radical equation).
You can use the "check solution" button when checking is not performed
automatically (i.e. when solving a linear equation, or after finding the inverse of
a matrix).

Graph operations
Graphing
Functions and curves may be graphed using the following buttons:

and

Much like "solve" and "solve all" buttons, graph buttons will give you either the
next single step or all the remaining steps required in order to convert an
equation (or inequality) into graphable form. Once the equation is ready to be
graphed, the graph window will be displayed, and the equation plotted.

A couple of points worth emphasizing about the graph window:
Graphs may be zoomed in or out by clicking on the corresponding zoom
buttons.
A particular portion of the graph may be zoomed in by selecting the
desired rectangular area within the graph window.
Individual graphs may be removed from the graph window by clicking on
their respective legend item; clicking again will make them reappear.
Graphs are not automatically closed when you refocus the worksheet: if
you click on the graph button again, a new graph window will appear. This
is useful for co mparison purposes. However, you need to remember to
close the graph window when you no longer need it.
