Instead of a function y(x) being defined explicitly in terms of the independent variable x, it is sometimes useful to
define both x and y in terms of a third variable, t say, known as a parameter. In this unit we explain how such
functions can be differentiated using a process known as parametric differentiation. (Mathtutor Video Tutorial)

Four questions on partial differentiation. The first two involve finding the first and second partial derivative of a polynomial in x and y. The third involves finding a first partial derivative using the chain rule. The fourth involves finding a second partial derivative involving the product rule.

Four questions on partial fractions. All questions involve proper fractions and contain a mixture of denominator types: distinct linear factors, repeated linear factors, a quadratic factor.

Peer Support (PS) has been running in the Department of Mathematics and Computer Science at the University of Leicester for the past 9 years. In this scheme students from the second and third years (called leaders from now on) help first year students in their efforts to assimilate first year material. The help occurs in small timetabled groups containing up to 8 or 10 first years and 2 to 4 leaders. In its first year the scheme had 6 second year leaders and now we have typically between 15 and 20 second and third year leaders.The number of first year students taking part in the scheme has also grown from about 10% of students in the early years to around 50% of students making some use of the scheme at some stage in the year.

The use of percentages is common in many aspects of commercial life. Interest rates, discounts, pay rises and so on, are all expressed using percentages. This leaflet revises the meaning of the term 'percentage', and shows how to calculate percentages, and how to convert expressions involving percentages into alternative forms.

In this unit we shall look at the meaning of percentages and carry out calculations involving percentages. We will also look at the use of the percentage button on calculators. (Mathtutor Video Tutorial)
