Freehand Function Tool

(Only in the Graphing Calculator app)

Activate the tool, then sketch the graph of a function.

For functions created with this tool:

  • It is possible to evaluate the functions at a point.

  • It is possible to create points on them.

  • It is not possible to calculate their derivatives.

  • It is possible to apply all the curve fitting commands, e.g. FitSin_Command.

  • It is possible to apply the Integral command e.g. Integral(f, 1, 5) to shade and calculate areas.
