# MATH 131: Applied Calculus I

Credit Hours

3

Prerequisites

Math Placement Test or MATH 118

Description

An introduction to differential and integral calculus, with an emphasis on applications. This course is intended for students in the life and social sciences, computer science, and business. Topics include: modeling change using functions including exponential and trigonometric functions, the concept of the derivative, computing the derivative, applications of the derivative to business and life, social, and computer sciences, and an introduction to integration.

(Students may not receive credit for both MATH 131 and 161 without permission of the department chairperson. Math 131 is not a substitute for Math 161.)

## Common Syllabus for MATH 131

Chapter 1 – A Library of Functions (1.5–2 weeks):

1.1 – Functions and Change
1.2 – Exponential Functions
1.3 – New Functions from Old

• Skip: the subsection on Shifts and Stretches and Odd and Even Symmetry.

• Comparison of long-run behavior of exponentials and polynomials.

1.7 – Introduction to Continuity

• Skip: the majority of the section.
• Understand the graphical viewpoint of continuity. (are there holes, breaks, or jumps in the graph?)

1.8 – Limits

• Skip: the subsection “Definition of Limit” (bottom of pg 58 – 59).
• Skip: the subsection “Definition of Continuity” (see comment on 1.7 above).
