Formulae and Functions

We spent some time looking at different ways to write the same formula. For instance, the formula for the area of a rectangle is generally written as A = lw . This formula can be rewritten as a function of l (l = A/w) or w (w = A/l), depending on which variable you are searching for.

The second part of class was dedicated to using the spreadsheets on the computers to help us with the rewriting of formulae.
