Question in STAT7008
Given a random variable $X$ normally distributed as $\operatorname{N}(m,\sigma^2)$ find probabilities $P(X \gt a),\; a \gt m;\;\;P(X \lt b),\;b \lt m$.

Question in Demos
Contains some extremely basic code to do symbolic differentiation: it can give the derivative of terms of the form $x^n$, $sin(x)$ and $cos(x)$, and apply the chain rule.

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 pisystem by each carbon within the conjugated chain. Students instructed to assume that there are 22 conjugated electrons in Betacarotene.

Question in CHY1201  SpectroscopyThe reduced masses are precalculated for this question and included in a list. It would be more elegant to program Numbas to permute atoms together to generate diatomic molecules while constraining the permutations to those which are chemically/physically reasonable, so as to allow calculation of each reduced mass directly from the atomic masses but organising this with high computational efficiency might be a significant programing task (add to "to do" list).

Question in CHY1201  Spectroscopy
Question requires students to interchange units of Hz with MHz, GHz, THz. Question is not very efficient at present frequencies spanning many orders of magnitude are generated by variables in a clumsy way. Could be improved by having frequency generated by a 10^((random(1000..4000)/1000) variable instead, for example.
