Enter functions f1(t),
g1(t), and
h1(t)
in the text input fields
marked "f1(t)=",
"g1(t)=", and
"h1(t)="
(Example:f1(t)=3cos 3t,
g1(t)=3sin 3t,
h1(t)=t)
Click the "Graph" button
(this button also refreshes the graph)
Rotate the graph by
clicking and dragging the mouse on the graph.
To see two curves graphed simultaneously:
Enter the second set of functions
f2(t),
g2(t), and
h2(t)
in the text input fields
marked
"f2(t)=",
"g2(t)=", and
"h2(t)="
Click (to its "on" state) the check box next
to this set of input fields
Click the "Graph" button
(Example:f1(t)=3cos 3t,
f1(t)=3sin 3t, and
f1(t)=t;
f2(t)=1+3t,
g2(t)=2-2t, and
h2(t)=3+t)
Up to 3 curves can be graphed simultaneously
To remove a curve from the graph, click (to its "off" state)
the check box next to the associated text input fields and click
the "Graph" button to refresh
To erase the graph and all input fields, click the
"Clear" button
There are two input fields which specify
bounds on the variables for the function:
The variable t
takes values between tmin
and tmax,
specified by the fields marked
"tmin=" and
"tmax=".
These two text input fields can accept any decimal number input.
