Parameter

If an expression contains some parameters, its graph varies by increasing or decreasing the parameter values. You can observe a dynamic graph by combining this functionality, the locus, and the after image.

Substitution of values for parameter

After clicking the parameter value part, input numerical values from keyboard.
The calculator will be displayed by double click, so you can also input from that.

Variation of parameter ,

Push up/down button at the right side of parameter.
The parameter continues to increase or decrease whilst the button remains pressed.
You can alter the velocity of increasing or decreasing at the bottom part of the Parameter area.

Range of parameter variation

The mode of increase or decrease (addition or multiplication) is configured by clicking [+].
The range of variation can be adjusted by one of the following ways.
- Click .
- Input numerical values from keyboard.
- Input on the calculator which will be displayed by double click.

Synchronization of parameter

Two or more parameters can be varied at the same time.
Set ON/OFF the synchronization by clicking the synchronization button at the right side of the parameter. The button at the pushing state means "ON".
When the synchronizations of some parameters are at "ON" state, if one of them is varied, another is also varied in the same range.

Fix a parameter value

By clicking a parameter letter, it will be at the pushing state and the value cannot be edited.
It can react by a second click.
