Calculus for Social Sciences 1 (Sections 03 and 04)

Exam #1

Thursday, Oct. 1, In Class

The first exam covers Chapter 1 (excluding Sections 1.4 and 1.7) and Sections 2.1 and 2.2. It is recommended that you go over homework problems (HW#1 - 3), your class notes and the quizzes. Many of the problems and questions we discuss in class are excellent examples of test questions. The solutions to your WebAssign problems on HW#1 - 3 can be seen by clicking "View Key" near the top of each assignment.

I have also listed some sample problems from the Chapter 1 and 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: Monday, Sept. 28th, 7:30 - 9:00 pm in O'Neil 112.
Please come prepared 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.
