How might we use the slope of the secant line in Figure 1(A) and limits to find the slope of the tangent line in Figure 1(B)? Rogawski Calculus Copyright © 2008 W. H. Freeman and Company
Figure 2 illustrates how the slope of the secant line PQ approaches the slope of the tangent line as Q approaches P. Rogawski Calculus Copyright © 2008 W. H. Freeman and Company
