'The Method of Fluxions' is the name given by Newton to his
of Differential Calculus, independently discovered by Leibnitz.
At its heart is the problem of trying to find the rate of change of a function.
If you look at this graph of x2, you will see that, when x
the graph is flat, but, as x increases, so the slope increases.
Newton decided that the solution to this problem was to define
the rate of change of a graph as the slope of the tangent
at a particular point.
