Catalog Course Description

Covers topics such as the calculus of vector-valued functions, the differential calculus of functions of more than one variable, directional derivatives, gradients, partial derivatives, multiple integration, vector fields, and line integrals. Various applications are covered throughout the course. Utilizes numerical, graphical, and algebraic approaches whenever possible. Requires a graphing calculator, with the TI-84 Plus series recommended, and access to an online homework management system.

### Goals, Topics, and Objectives

Goal Statement

- To study the nature and significance of calculus for students of science, technology, engineering, and mathematics disciplines.
- To demonstrate various applications of calculus to problems from the social sciences, physical sciences, and engineering.
- To present an exposition of calculus that incorporates graphical, numerical, and algebraic analysis, without undue emphasis on theoretical abstraction or routine mechanical manipulation.
- To use technology to illustrate calculus concepts and verify calculus solutions to application problems.
- To provide students with an exposure to the logical reasoning of mathematics.

Core Course Topics

- Vectors and Vector -Valued Functions
- Perform vector addition and scalar multiplication of vectors algebraically and geometrically.
- Identify and solve problems involving vectors in the plane and in 3-space both geometrically and algebraically.
- Compute the dot product for vectors in 2 and 3 dimensions and the cross product for vectors in 3 dimensions.
- Use the dot and cross products in applications such as computing the angle between 2 vectors, vector projections, scalar components, work and torque.
- Construct vector-valued functions in order to describe lines and curves in 3-space.
- Determine limits of vector-valued functions using numerical, algebraic and graphical methods.
- Determine continuity or discontinuity of vector-valued functions.
- Determine derivatives and integrals of vector-valued functions.
- Find the vector components of velocity and acceleration for particle motion in 3-space.
- Find the length of a curve in 3-space and be able to parameterize a given curve with respect to arc length.
- For a given curve, determine the unit tangent, unit normal, unit binormal and curvature.

- Functions of Several Variables
- Determine the equation of a plane in 3-space using both the vector form and the scalar form.

### Assessment and Requirements

Assessment of Academic Achievement

- All students will be required to complete a comprehensive final examination that assesses the learning of all course objectives. This final exam must be weighted in a manner so that this exam score is worth a minimum of fifteen percent (15%) of the final course grade.
- In selected semesters this final exam may be a common final exam administered to all sections of Math 280.
- All students will be required to complete online homework. This online homework must be weighted in such a manner so that it is worth between six percent (6%) and twelve percent (12%) of the final course grade.
- Application problems must not only be included on chapter exams but also on the final exam.
- Additional assessment of student achievement may include assignments, quizzes and exams.Some exam problems should require the use of a graphing calculator.

General Course Requirements and Recommendations

- A graphing calculator is required of each student. The Mathematics Department recommends and uses the TI/84 Series.
- Students will be expected to use 3-dimensional graphing software such as the DP-Graph computer program or other software as approved by the Mathematics Upper Department course committee.
- Access to an online homework management system is also required.
- Application problems must be covered in all mathematics courses. Every section in any course outline that includes application problems must be covered.
