BC -2 Semester Review

This is a beginning. It is not intended as a complete review. It is a reminder of the many types of problems we have done this semester and it is a guide for active study. Remember to review old tests and quizzes, problems from the book, and handouts, as well as chapter review sections. Pace yourself while studying during the coming week or so. Remember topics that were clear in January still deserve some time now. Also, please spend some time thinking about the conceptual meaning behind the problems on the following pages and not just the mechanics of getting through each problem.

More goodies to do – to complement the problems in the book, not replace them:

(1) Consider the function , where a and b are constants.

(a) Find all critical points of f.

(b) For what values of a and b does f have exactly one critical point? What are the coordinates of this one critical point, and is it a local maximum, local minimum, or neither?

(c) For what values of a and b does f have exactly three critical points? What are the coordinates of these critical points? Which are local maxima, which are local minima, and which are neither?

(2) Draw the graph of a continuous function that has three different types of critical points on the interval [–5, 5].

(4) A rectangle of fixed perimeter 36 inches is rotated around one of its sides, sweeping out a figure in the shape of a right circular cylinder. What is the maximum possible volume of that cylinder?

(5) A rectangular plot of land containing 216 square meters of area is to be enclosed by a fence and divided into three equal parts by two other fences that will both run parallel to the same side of the rectangular plot. What dimensions for the entire rectangular plot require the smallest total amount of fencing? How much total fencing will be needed?

(6) A commuter train carries 600 passengers each day from a suburb to a city. The cost to ride the train is $4.50 per person.

(15) You and your bff are driving along a twisty dirt road in your old "beater" car. The speedometer on this car works but not the odometer. To determine how long this particular road is, you record the car's speed, s, in feet per second (being conscientious mathematics students, you converted from miles per hour as you recorded the data) at different times, t, in seconds during the two-minute time interval you were on the road. Those results are shown in the table below.

t / 0 / 10 / 20 / 30 / 40 / 50 / 60 / 70 / 80 / 90 / 100 / 110 / 120
s / 0 / 44 / 35 / 15 / 30 / 44 / 35 / 15 / 22 / 35 / 44 / 30 / 35
