Characteristic poly, eigenvalues and eigenvectors 3x3, digonailsability (non-randomised) Ready to useQuestion in Ugur's workspace
Example of an explore mode question. Student is given a 3x3 matrix and is asked to find the characteristic polynomial and eigenvalues, and then eigenvectors for each eigenvalue. The part asking for eigenvectors can be repeated as often as the student wants, to be used for different eigenvalues.
Assessed: calculating characteristic polynomial and eigenvectors.
Feature: any correct eigenvalue will be recognised by the marking algorithm, even multiples of the obvious one(s) (which can be read off from the reduced row echelon form)
Randomisation: Not randomised, just using particular matrices. I am still working on how to randomise this for 3x3; a randomised 2x2 version exists. I have several different versions for 3x3 (not all published yet), so I could make a random choice between these in a test.
The implementation uses linear algebra functions such as "find reduced echelon form" or "find kernel of a reduced echelon form", from the extension "linalg2".

Question in SIT316
This question uses a Geogebra applet to solve a linear program with two variables using the graphical method. It contains three steps:
- Construct the feasible area (polygon) by adding the constraints one by one. The students can see what happens when the constraints are added.
- Add the objective function, and the level set of the objective value is shown, as well as its (normalised) gradient.
- Compute the optimal solution by moving the level set of the objective around.
