Chapter 2ET, Slide 3 Figure 2.9: We made the graph of y´ = ƒ´(x) in (b) by plotting slopes from the graph of y = f (x) in (a). The vertical coordinate of B´ is the slope at B and so on. The graph of y´ = f ´(x) is a visual record of how the slope of f changes with x.

(b) The graphs of s and v as functions of time; s is largest when v = ds/dt = 0. The graph of s is not the path of the rock: It is a plot of height versus time. The slope of the plot is the rock’s velocity graphed here as a straight line.

Chapter 2ET, Slide 7 Figure 2.28: When gear A makes x turns, gear B makes u turns and gear C makes y turns. By comparing circumferences or counting teeth, we see that y = u/2 and u = 3x, so y = 3x/2. Thus, dy/du = 1/2, du/dx = 3, and dy/dx = 3/2 = (dy/du)(du/dx).
