A tutorial video from the Autograph team. The concepts learnt in the investigation of areas can also be applied to volumes of revolution. Suppose the region under the curve y = f(x) between x = a and x = b is revolved around the x-axis to form a solid. What is the volume of this solid? How can we approximate the volume?

Using ICT in Maths. How many lines of symmetry does a cube have? The 35th in Mr Barton's Autograph Video tutorial series. We make good use out of our cube again this week, this time by taking a look at the surprisingly tricky question of: 'how many planes of symmetry does a cube have?'. Autograph's 3D mode provides a lovely way of displaying the answer. Oh, and for the record, I got this question wrong!
