Enter a function f (x) in the text input field
marked "f (x)="
(Example:f (x) = x2)
Click the "Graph" button
(this button also refreshes the graph)
Select values for x1 and x2
(Example:x1=0, x2=1)
This can be done in either of two ways:
Use the mouse to click and drag the
red points on the graph --
the points follow the graph of f (x), and the
values of x1 and x2
correspond to the horizontal positions of the points on graph
Enter the values in the text input fields marked
"x1=" and
"x2=",
and click the
"Graph" button to refresh
To erase the graph and all input fields (setting
x1 and x2 to default values), click the
"Clear" button
The text input field marked "f (x)=" can accept
a wide variety of expressions to represent functions.
The text input fields marked
"x1=" and
"x2="
can accept a real number in decimal
notation. The
buttons under the graph
allow various manipulations of
the graph coordinates.
