Office: I'm stored below all the other mathematicians on the 3-rd floor of DeMoss Hall.

Note there is a complete schedule posted further down this page which shows both office hourse and my teaching schedule.

- (Math 121) College Algebra.
- (Math 126) Applied Calculus
- (Math 221) Applied Linear Algebra.
- (Math 321) Linear Algebra.
- (Math 422) Abstract Algebra II.
- (Math 200) Transition to Advanced Mathematics.
- (Physics 231) University Physics I
- (Physics 232) Physics II: Electricity and Magnetism.
- Introduction to Mathematical Physics.
- (Math 131) Calculus I.
- (Math 132) Calculus II.
- (Math 231) Calculus III
- (Math 334) Differential Equations (MATH 334)
- (Math 331) Complex Analysis
- (Math 332) Advanced Calculus (2009).[needs update, have revised course twice since then]
- (MATH 497) Special Topics in Elementary Differential Geometry.

If a student wishes to learn material past the standard core course at my school and it happens that their interest aligns with my own then I try to set up a Math 495 course with an appropriate title. In order to justify such a course the student needs to have a very solid academic history.

The files posted below are some of the lecture notes from previous courses that I've taught. I usually update the course notes each time I teach. I post these here for reference sake. My apologies for the errors,

- Calculus I and II. Calculus II's chapters 15 , 16 , 17 , 18 , 19 were reformatted from earlier, inferior, word formatted notes.
- My calculus III notes contain many pictures and hand-written calculations. These tend to make the files bigger. For students taking Math 231, there is a master file which has a table of contents which navigates the file. That feature is lost as I divide these for better download size. If you are my student then please save a copy of the file posted in Course Content for your convenience as the semester progresses.

(superstringtheory.com is a good website for accurate info on strings from a relatively non-technical viewpoint, truth of matter is there is no purely intuitive theory of physics, we need math, a correct description is necessarily technical. If you've had my classes you know I take this viewpoint in most venues, notation is to be embraced not skirted)

If you are interested in attending a local math meeting sometime this semester please let me know. I don't go as often now since the universities travel policy now requires me to rent a car rather than drive my own. Anyway, if you ask early enough we may find the time to make a trip a reality. Usually the department goes to the MAA meeting each Fall or Spring.

My thesis is in the area of supermathematics. However, recently my interests have turned to two main areas:

I should mention, I do have many questions in supermathematics. However, you need to take all the required courses at LU before we can even properly begin to develop background so we can then discuss the questions. So, this means it is a rare student who has the option to attempt this. Ideally, I'll find some free time to distill the questions down to a form which doesn't require all the background. Sadly, at the moment, I am not there. So I recommend the other questions for the time being.

The primary purpose of this site is to provide my students (and myself) with a permanent easy to find archive of coursework done under my supervision. Also, it serves as an advertisement for my math/physics research hence the site name. Any questions, comments or clarifications may be sent to testbetter@yahoo.com, Thanks.
