To accompany these problems, this Plus article discusses how the cubic graph $y=x^3$ lies behind the hidden dome of St Paul's Cathedral. You might also like to watch this video from Plus about a very special curve.
You can watch a recording of the webinar in which we discussed the mathematical thinking which can be prompted by these problems.
