1.5 Function Notation
... independent variable, or argument of f , whereas y is often called the dependent variable. As we shall see, the process of a function f is usually described using an algebraic formula. For example, suppose a function f takes a real number and performs the following two steps, in sequence 1. multiply ...

He replaced this with a rigorous notion called a “limit”, an idea already used by Newton and others but never made explicitly clear. Limits allowed ...

LESSON 21 - Math @ Purdue
... ∆y is the actual change the function f (x), which is our goal. In an ideal world, we could compute this directly for any potential ∆x. But, in general, this is difficult to compute even with a calculator so we settle for an approximation of ∆y instead. Observe that ∆y f (x + ∆x) − f (x) ...
