Calculus for Social Sciences 1 (Sections 01 and 02)

Exam #2

Thursday, Oct. 25, In Class

The second exam covers all of Chapter 2 (including Sections 2.1 and 2.2). It is recommended that you go over homework problems (HW#4 - 6) as well as your class notes. Many of the problems and questions we discuss in class are excellent examples of test questions. I have also listed some sample problems from the Chapter 2 Review Exercises below. The odd answers are in the back of the book while the evens are listed here. The Concept-Check at the end of each chapter (before the exercises) is also a source for good questions. The exam will be designed to take roughly one hour although you will have the full class period (plus a little extra) if necessary.

Exam Review Session: Tuesday, Oct. 23, 6:00 - 7:30 pm in O'Neil 112.
Please come with specific questions.

Note: You will be given a scientific calculator for the exam which does NOT have graphing capabilities so be prepared to answer questions without your personal calculator.

Chapter 2 Review Exercises, pp. 176 - 178
Problems:   1, 3, 4, 5, 7, 11, 12, 13, 15, 16, 19, 21, 23, 25, 27, 28 (a and b), 31, 32, 33, 34, 35 (a and b), 37, 38, 39, 40, 43

The answers to the evens are:
4.   0
12.   1/3
16.   -1
28.   (a) f'(2) = 10, (b) y = 10x - 16
32.   Your graph should be positive (above the x-axis) until a small positive value, then become negative (below the x-axis).
34.   Your graph should be discontinuous at the cusp.
38.   a = f, b = f'' and c = f'.
40.   This is just like Nixon's statement on inflation. The first derivative of the cost of living function is positive since the cost rises but the second derivative is negative because it is rising at a slower rate (slopes decrease means concave down).
