A function links an input value to an output value. Functions are written in function notation with the name of the function (usually f or g), a variable written in brackets and an expression ...

To promote fluency with functions representing proportional relationships, students begin by interpreting function notation in context.

In this paper, we derive Maxwell’s equations using a well-established approach for deriving time-dependent differential equations from static laws. The derivation uses the standard Heaviside notation.
