Differentiation of functions defined parametrically resources

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.
