##
**Stationary points **

**This activity shows students how to use differentiation to find stationary points on the curves of polynomial functions. It includes the use of to determine the nature of the stationary point. Students will learn how to use this and other information to sketch the curves, then use graphic calculators to check their answers. **

**Mean values**

**Students learn how to find the mean values of quantities varying with time. This involves finding the area under graphs, initially by using geometrical formulae for areas. It is followed by the use of integration in a variety of real life situations.**
