This video continues directly on from __Rates of Change and Differentiation__, in which the concept of a rate of change was introduced and we investigated the need to know the value of instantaneous rates of change. The term ‘to differentiate’ was also discussed. Differentiation is the process of calculating a rate of change. This video describes how to differentiate a specific class of equations known as polynomials. So make sure you’ve seen __Rates of Change and Differentiation__ recently before watching this video.

This video also builds upon earlier algebraic concepts such as __indices__, including __negative indices__, and __linear equations__. It is important to be comfortable with algebra and manipulating algebraic equations before continuing with calculus, so watch those videos again if you need to, then come back.
