  • Julien's copy of Solve a linear programming problem

    by Julien Ugon and 3 others

    Student is given a set of constraints for a linear program. Asked to enter the constraints as inequalities, and then to identify the optimal solution.

    Problem with solving the simultaneous equations gven by the constraints - too unwieldy and not given enough marks for doing so. Best if the point of intersection is given graphically by putting the mouse over the intersection.

  • Johan's copy of Mark equations

    by Johan Maertens and 3 others

    All the answers in this question are equations. In order to mark each equation, Numbas needs to pick some values that satisfy the equation and some that don't, and check that the student's answer agrees with the expected answer.

    Any equation with the same solution set as the expected answer will be marked correct.
