The Freehand Shape Tool lets you either sketch a function, or you can draw a freehand circle, segment or polygon and it will be recognized and converted to an exact shape. If a function f is created, you can compute its value at certain point, place a point on it or perform some transformations. Derivatives for these functions are not supported (tangents are supported as a numerical approximation)

Notes:
  • You can use all the curve fitting commands on functions created by this Tool, e.g. FitSin_Command
  • You can use the Integral command on functions created with this tool e.g. Integral(f, 1, 5) to shade under it and find the area
