If we had a function for the [b]area[/b], A, we could take the derivative to find a function for the [b]height[/b], y. This process is called [i]differentiation[/i].[br][br]Inversely, if we have a function for the [b]height[/b], y, we could take the [b]ANTI[/b]-derivative to find a function for the [b]area[/b], A. Thus, for any function we can determine the area under its curve with the antiderivative. This process is called [i]integration[/i].
