MA005: Calculus I

We estimated the slope of a line tangent to the graph of a function at a point and constructed a new function which was the slope of the line tangent to the graph of a function at each point.  In both cases, before we could calculate a slope, we had to estimate the tangent line from the graph of the function, a method which required an accurate graph and good estimating.  In this section, we will start to look at a more precise method of finding the slope of a tangent line which does not require a graph or any estimation by us.  We will start with a nonapplied problem and then look at two applications of the same idea.
