GeoGebra Graph Input

The goal of this project is to integrate GeoGebra into LON-CAPA as a means to grade free-form graph input. Authors can provide rules for functions, their integrals, and their first and second derivatives, as well as tolerances on the expected values and inequalities. Hints can be provided for rules that are not fulfilled. Instead of absolute x-values for their ranges, rules can have labels as boundaries, which are detected and evaluated by the grading algorithm.

Below are some examples of what already works.
