Calculus is the mathematics of change. In algebra we covered linear functions, the word linear refers to straight lines, straight lines represent change, but change that is at a constant rate (i.e. like a car driving at a constant speed). In calculus we will start to look at functions and lines where the changeā¦ changes! For example, if a car driving at a constant speed is represented by a straight linear line, then we will use calculus to look at a car driving where its speed is changing (like if it was going down hills or being stuck behind cyclists etc.)
