Question in CHY1201 - SpectroscopyQuestion requires students to themselves calculate how many electrons are in the conjugated system for the molecules included in this question. As is standard for applications of the "particle in a box" model, the embedded assumption is that one electron is donated to the pi-system by each carbon within the conjugated chain. Students instructed to assume that there are 22 conjugated electrons in Beta-carotene.

Question in HELM books
evaluate a function with randomised alphanumeric expressions as inputs.
-
A custom marking algorithm picks out the names of the constants of integration that the student has used in their answer, and tries mapping them to every permutation of the constants used in the expected answer. The version that agrees the most with the expected answer is used for testing equivalence.
If the student uses fewer constants of integration, it still works (but they must be wrong), and if they use too many, it's still marked correct if the other variables have no impact on the result. For example, adding +0t to an expression which otherwise doesn't use t would have no impact.

This uses an embedded Geogebra graph of a sine curve y=asin(bx+c)+d with random coefficients set by NUMBAS.
-
Replace two forces with a equivalent force-couple system at a specified point.

Question in HELM books
Simplify (a) a fully-factorised fraction with common factors, and (b) a fraction where the numerator is a product and the denominator a sum sharing the same variables (that cannot be simplified). The variables are randomised. Part of HELM book 1.4

Question in Alexander's workspace
The statement contains two blank geogebra applets: one with the computer algebra view, which can be used as a calculator, and the other with algebra and geometry views.
There are custom functions which set the perspective of a geogebra applet and show the toolbar or algebra input line. These will probably be included in the geogebra extension eventually.

Question in Bin
A measurement is performed multiple times for the same object, the student will
- calculate the mean result
- calculate the standard error on the mean
- write the mean±error to the correct precision as defined by the error written to 1 significant figure
Advice is provided including on performing the calculations in Python or spreedsheets together with further reading.

Question in Maura's workspace
A straightforward test of encrypting and decrypting an eight-letter message with the Vigenère Cipher using a four-letter key. Message letters are generated uniformly at random from the English alphabet, as are the key letters. Students are expected to be able to map English letters onto elements of Z26 in the usual order.

A straightforward test of encrypting and decrypting an eight-bit message with the Vernam Cipher. The message and the key are uniform and independently generated eight-bit strings.
-
Question in Maura's workspace
A straightforward test of encrypting and decrypting an eight-letter message with the Substitution Cipher. Message letters are generated uniformly at random from the English alphabet and the key is a uniformly chosen random permutation of the alphabet. Students are expected to be able to map English letters onto elements of Z26 in the usual order.
