Curve sketching can be a very useful tool when you are solving equations or inequalities, or for when you are wanting to find maximum or minimum values. The problems in this feature will offer you the opportunity to develop your skills in
using this valuable tool.
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.
