Material created by students working with the School of Mathematics, Statistics & Physics E-Learning Unit at Newcastle University over the summer of 2017, to support students making the transition from school to university.

Christopher Graham on Extract common factors of polynomials1 month, 3 weeks ago

The pattern match on line 10 of the custom function no longer appears to handle the commutativity of the expression, despite using the doCommute option. E.g. $2*(17x+2)$ is not acccepted, however $(17x+2)*2$ is.

Checkpointing before looking at the problem with the user defined function mark_factorised which no longer appears to be functioning correctly.

Looks like there was an off-by-one error.

You're right! I've fixed it, and improved the TeX. Worried that I let that slip by!

In part b does not accept correct answer. Mistake also shown in the solutions.

I think there is a sign error in the second equation in part b.

I've changed the definition of x2 to make sure the sales are always non-negative.

I've fixed part h - I was missing a plus-or-minus in the matching pattern.

J. Richard Snape on Substitute values into formulas1 year ago

Part (b) uses the random variable n={0..4}, but that can give negative sales in a year which doesn't make much sense.  I think that the variable definition has been copied over from a different word type question and should actually be allowed to run {2..5}

Thanks for this fantastic question set in "Transition to University".  I'm trialling using them in my teaching this year.  I have a tiny problem with part h in this question - for some reason when I use it when a student enters a correct answer it marks it wrong, giving feedback that it can be further simplified.  I attach a screenshot - not sure what rule is triggering this as even the 419 constant is prime, so I can't see any further gathering of terms possible.  I'll try to debug myself, but any help would be appreciated :)  It seems to be using "all" for simplification in the marking, but so are other parts in this question that work fine.
