### Derivatives (Calculus) Made Simple

What is life but a sea of change?

Mathematically, when we speak of change, we are speaking about rates … one thing changing compared with another.

Rates are easy to calculate when the situation does not vary; when you travel at a constant speed, for example.

But, what happens when your *rate* of change is itelf *changing?* How do you handle that?

Welcome to the world of calculus and, in particular, derivatives … which are ways of calculating rates of change as a *function* (as something that changes).
