6 questions which introduce the user to the Numbas system.

Substitute the numeric or algebraic definition of a variable into different expressions. 

Draws a triangle based on 3 input points. Calculates length, area, perimeter, heights and internal angles

Given a graph of some function $f(x)$ (a cubic), the student is asked to write the coordinates of the maximum and minimum points. The student then finds the maximum and minimum points of a second cubic function without using a graph, by finding the derivative, solving the quadratic equation that results from setting the derivative equal to zero, and finally testing the value of the second derivative.

Solve a system of three simultaneous linear equations

Basic solving of linear equations.
