Finding where two graphs intersect
You can now do this very easily in Graphmatica
 After graphing the two equations, adjust
your viewing window so that the intersection point(s) show up on the screen.
 From the Point menu select Find Intersection...
 Specify which graphs you want to intersect
in the dialog box and click the Calculate button. Graphmatica does the rest.

Accurately finding when a graph takes on a particular y value
You can now do this very easily in Graphmatica.
 After graphing the equation, adjust
your window so that the y value that you want to attain is actually shown on the screen. This is important, as
Graphmatica will not be able to compute the required value of x otherwise.
 From the Point Menu, select the Evaluate...
command
 Select the equation your are solving,
and enter the y value you have in the appropriate box.
 Click calculate and Graphmatica will
compute the value of x required to produce that y value.

Accurately plugging in an x value into an equation
 Select Evaluate...
from the Point menu. A dialog box will appear and you can enter
the x value you want to enter. Make sure you enter the x value in the first box as indicated below.
 Select the equation you want to work
with.
 Hit ENTER
or click on the Calculate button, the y value that corresponds to that x value will appear.

Hiding or deleting a graph
Select the graph that
you want to hide or delete. You will know that you have selected the correct graph when the status bar at the bottom
of the screen indicates a graph has been selected.
When the graph is correctly selected, type CTRLH to hide the graph or CTRLD
to delete it. CTRLH erases the graph from the screen but does not
delete it from the graph menu list. CTRLD erases the graph from the screen AND deletes
it from the graph menu list. You can also click the delete button to delete and the hide button to hide graphs.

Entering lnx and e^{x} into Graphmatica
The lnx
function can be entered as:
y=ln(x) The parentheses are necessary
y=ln(x^{2}+4)
would be entered as y=ln(x^2+4)
The exponential function e^{x}
can be entered as:
y=e^x or y=exp(x)
If you have something like e^{2x+3}, you would enter it as
y=e^(2x+3)

What does 4.576*10^5 or 5.3*10^13mean?
When you see this, Graphmatica is using
Scientific Notation. The examples given mean the following:
4.56*10^5 = 4.56x10^{5}
5.3*10^13 = 5.3x10^{13}
^{Note that Excel will handle this
differently. Excel uses the E notation, which is not to be confused with the natural base, e. For example, in
Excel}
4.56E5 = 4.56x10^{5}
5.3E+13 = 5.3x10^{13}
