			NUMERICALLY EVALUATING A POINT
The Evaluate command in the point menu allows you to quickly find the value of
any equation you've entered at a specific point. First choose an equation from
the queue by selecting it in the equation combobox. (If you do not choose an
equation, Graphmatica will select the last one graphed for you.) Then choose
the Evaluate command from the Point menu.

You will be asked to enter a value for the selected equation's independent
variable. Any expression that evaluates to a constant is OK, including
fractions and constants. Graphmatica will calculate the value of the dependent
variable(s) at this point and display the result. For function families that
use the parameter 'a', only the starting value of 'a' will be used, since only
one result can be displayed. (Note that if an error occurs when evaluating at
the point, a message will be displayed on the bottom line regardless of the
state of the Warning Messages option.) Press any key to type in another point
to evaluate. When you want to stop evaluating points, press ESC to return to
the menu.
				Set IV COMMAND
This option allows you to choose the initial-value point for an ODE
approximation using the crosshairs. You must type in or select a differential
equation in the listbox first. See the Graphing help or manual for details.

			    THE COORDINATE CURSOR

You can use this feature to find the numerical coordinates of any point on-
screen. To turn on the coordinate cursor:
 + Select Cursor from the Point menu, or
 + Hold down the right mouse button as you move the mouse over the grid.

The crosshairs respond to both the mouse and the arrow keys. As you move the
crosshairs, the coordinates are displayed at the bottom of the screen. To exit
the coordinate cursor, click either mouse button or press ESC. Using the
arrows keys, the cursor moves about 20 pixels with each keypress, so you can
move rapidly from one side of the screen to the other. To move the crosshair
one pixel at a time, hold down the Ctrl key and then press the arrow keys.

When you move the cursor close enough to one of the curves on-screen, it will
automatically "lock on" to make it easier to trace the path of the curve. When
this happens, the equation of the curve being traced is also displayed in the
status bar. The crosshair will stick to the curve you chose, even if it
intersects other graphs, as long as you move the cursor gently in the general
direction of the curve. To release the cursor from a curve, move perpendicular
to the slope of the curve at that point, or just move quickly in any
direction.
