VARIABLES PANEL

The variables panel allows you to modify the value of any free variable and update several graphs without editing a single equation.

Edit boxes

In the top ("a=") section,

from is the value to start calculating the value of the parameter a from.
tois the maximum value a can take (or minimum if step by is negative)
step byis the amount to increment a by between each graph.

Uses of a are described in Graphing Families of Functions.

b = is the value to assign to the free variable b
c = is the value to assign to the free variable c
j = is the value to assign to the free variable j
k = is the value to assign to the free variable k

Uses of b, c, j, and k are described in Using Free Variables.

The other lines are reminders of the values of the built-in constants.

Buttons

Update finds all equations using the free variables you have most recently modified and makes a copy of each one using the new value(s), then graphs the new equations. This allows you to modify the value of a parameter in several equations simultaneously without editing any of them!
