This tutorial shows how to build parametric graphs on formula.
Select menu item
<Fit><Add Function>.
The 'Build function on formula' dialog appears.
To build simple graph, click the [Formula] tab and set Y(u,v) = 2+u-sqrt(u), X(u,v) = 12+2*sin(u*5).
Click
Apply
.
To build graph with parameter 'v', click the [Formula] tab and set Y(u,v) = 5+4*cos(u*v), X(u,v)= 5+4*sin(u).
Click the [Parameters] tab and select item 'Use parameter v' checked.
Set range of parameter 'v'.
Click
Apply
