This is the final element of the support for mock exam preparation. The question concerned is 'Calculus Associated with a Cubic'.
Though most of the marks are for problem solving with standard calculus for polynomials the first 3 marks are concerned with a general point of inflection. This has not been examined on our old MEI syllabus and I can find no mention of it in our new textbooks. I have recorded a 10 minute lesson which will hopefully help you get to grips with it.
