# Undergraduate Linear Algebra Courses

**Note: the links to the course webpages are broken. You can find a short description of all of our courses at the UW-Guide.**

In order to complete the major in mathematics you must take a course in linear algebra. At UW-Madison we offer several versions of linear algebra. **Note that in all versions of the major and certificate, only ONE of the following courses may be used to fulfill any of the requirements.** The purpose of this page is to describe the essential differences between the courses.

## Math 320 Linear Algebra and Differential Equations

Math 320 covers both some linear algebra and some differential equation theory. As such, students who complete this course can consider themselves as also having some of the content of Math 319 (introduction to differential equations). The difference between this course and taking both 319 and 340 is that one will be able to see how theory and applications unite in a meaningful way. This course also lends itself to the 321-322 applied analysis sequence.

Students who have completed Math 320 will need to complete either 1) Math 421 or 2) the applied analysis sequence Math 321 and 322 or Math 467 before moving on to the 500 level.

In summary math 320 is:

- Useful for students interested in classical applications of mathematics (i.e., physics, engineering, continuous modeling, etc.)
- Covers material in Math 319 and therefore
**credit for only one of Math 319 and 320 can be applied to the math major or certificate**. - Not by itstelf sufficient for taking advanced math classes.
- Good introduction to how theory and applications support each other.
**Is offered with an honors(!) version. This version is suggested for potential math majors and those in the AMEP program**.- Suggested further courses are
- The applied analysis sequence Math 321 - math 322 which covers more mathematics useful for traditional applications.
- Dynamical systems Math 415 which includes both continuous and discrete models of changing systems.
- Theory of Calculus Math 421 for an introduction to more formal mathematical arguments.

## Math 340 Elementary Matrix and Linear Algebra

Math 340 a basic linear algebra course which focuses on vectors as ordered sets of real numbers and linear operators as matrices. In this course the focus is typically on computational aspects of the subject with some lighter treatment of the more theoretical points.

Students who complete this course and would also like exposure to differential equations should consider Math 319.

Students who have completed Math 320 will need to complete either 1) Math 421 or 2) the applied analysis sequence Math 321 and 322 or Math 467 before moving on to the 500 level.

In summary math 340 is:

- Ideal for students who need functional knowledge of basic matrix algebra in particular those looking for applications featuring discrete mathematics (i.e., computer science and possibly statistics).
- Not by itself sufficient for enrollment in advance Math courses
- Subsequent math courses:

## Math 341 Linear Algebra

Math 341 is a linear algebra course which is also meant to be an introduction to proofs and proofwriting. The linear algebra content of the course is more robust than any of the others listed on this page. Students who complete the course should be well prepared to move onto any upper level course, in particular Math 521, 541, or 551.

It is the recommended linear algebra course for majors interested in moving to advanced undergraduate courses quickly

Students who complete this course and would also like exposure to differential equations should consider Math 319.

In summary math 341 is:

- A good introduction to proofs and proofwriting.
- Will give students access to advanced level math courses.
- Subsequent courses:
- Math 421 for another exposure to formal mathematical arguments at the introductory level.
- Any math course above the 500 level (possibly assuming other prereqs).

## Math 375 Topics in Multi-Variable Calculus and Linear Algebra

Math 375 is an Honors course which features the role that linear algebra has in multivariable calculus. Students who have completed Math 234 (Calculus - Functions of Several Variables) may not take this course.

Students who complete this course are also expected to complete the sequel course: Math 376.

In summary Math 375 is:

**Honors level.**- Enrollment is by permission only.
- Not open to students who have credit for Math 234.
- A good introduction to proofs and proofwriting.
- Students who complete Math 375 and not Math 376 are not considered to have completed the content of Math 234! So by enrolling in Math 375 in the Fall, you should be prepared to enroll in Math 376 in the spring, or Math 234 in order to complete multivariate calculus.
