### Title

Calculus of Several Variables.

### (Credit Hours:Lecture Hours:Lab Hours)

(3:3:0)

### Offered

F, W, Sp, Su

### Prerequisite

### Description

Partial differentiation, the Jacobian matrix, and integral theorems of vector calculus.

## Desired Learning Outcomes

This course is aimed at students majoring in mathematical and physical sciences, and engineering, and students minoring in mathematics or mathematical education. Calculus is the foundation for most of the mathematics studied at the university level. The mastery of calculus requires well-developed manipulative skills, clear conceptual understanding, and the ability to model phenomena in a variety of settings. Calculus of several variables extends the concepts of limit, integral, and derivative from one dimension to higher dimensional settings and is therefore fundamental for many fields of mathematics. This course contributes to all the expected learning outcomes of the Mathematics BS (see [[1]]).

### Prerequisites

Students are expected to have completed Math 113.

### Minimal learning outcomes

Students should achieve mastery of the topics below. This means that they should know all relevant definitions, full statements of the major theorems, and examples of the various concepts. Further, students should be able to solve non-trivial problems related to these concepts, and prove simple theorems in analogy to proofs given by the instructor.
