The Grading package provides tools for grading.

It is primarily used for grading plots of simple functions. The GradePlot command offers this functionality and allows error tolerances based on the plot's ranges.

Representations of elements to be graded are created through constructor commands such as QuadraticFunction. The generated objects can be constructed from mathematical expressions or data points, such as those obtained through embedded plot components.

Additional utility commands are available in this package for examining or drawing an object created by one of the constructors.

The commands in the Grading package are:

$\mathrm{with}\left(\mathrm{Grading}\right)\:$

$\mathrm{L1}≔\mathrm{LinearFunction}\left(3x-4\right)$

$\mathrm{L1}≔\mathrm{<<\; LinearFunction:\; 3*x-4>>}$

$\mathrm{L2}≔\mathrm{LinearFunction}\left(\left[0\&comma;-4\right]\&comma;\left[4\&comma;7.97\right]\right)$

$\mathrm{L2}≔\mathrm{<<\; LinearFunction:\; 2.992500000*v-4>>}$

$\mathrm{GetExpression}\left(\mathrm{L1}\right)$

$3x-4,x$

$\mathrm{GetData}\left(\mathrm{L2}\right)$

$\left[\mathrm{<<\; GridPoint:\; [0,\; -4]>>}\&comma;\mathrm{<<\; GridPoint:\; [4,\; 7.97]>>}\right]$

$\mathrm{plotview}≔\left[-10..10\&comma;-10..10\right]$

$\mathrm{plotview}≔\left[\mathrm{-10}..10\&comma;\mathrm{-10}..10\right]$

$\mathrm{Draw}\left(\mathrm{L1}\&comma;\mathrm{plotview}\right)$

$\mathrm{GradePlot}\left(\mathrm{L1}\&comma;\mathrm{L2}\&comma;\mathrm{plotview}\right)$

The Grading package was introduced in Maple 18.
