2.8 Differentiation Rules
By the end of your studying, you should know:
On-screen applet instructions: The table displayed shows the values of the difference quotients of fg for the given value of h and at various points x. The value of h may be controlled by the slider so that one can investigate the limit of the difference quotients as h → 0. The hide/show button at the bottom will show an additional column of values for comparison with the derivative fg′ + f′g.
ExamplesDifferentiate h(x) = (x + 2)4.
Robert throws a rock into a lake, which creates a circle of ripples which moves away from the point of impact at a constant speed of 50 centimeters per second. What is the rate of change in the area of the circle after 1 second? After 10 seconds? After t seconds?
