MAT 271-01 Foundations of Higher Math

- MW 8:30-9:45am in SBS E126
- Textbook:
*Mathematical Reasoning: Writing and Proof*by Ted Sundstrom. Download (free) and buy a cheap paper copy at https://sites.google.com/site/mathematicalreasoning3ed/ . I recommend the paper copy, it's very convenient! (Winner of the first annual Mathematical Association of America Daniel Solow Author's Award.) - Syllabus
- Calendar

- Desmos (https://www.desmos.com/) basic, simple, fast, easy-to-use web-based graphing calculator. Enables users to share calculations and graphs with each other. Desmos is intendeded for basic calculations, for more advanced math and programming try CoCalc.
- CoCalc (https://cocalc.com/), formerly called
**Sage Math Cloud**. Free, or pay if you choose to. Enables users to perform advanced math calculations and write programs directly on the web without installing anything. Provides**Sage**, a free computer algebra system for calculus, differential equations, linear algebra, number theory, abstract algebra, ... with 2D and 3D graphics. Also provides**R**for statistics,**Octave**(a command line program similar to MATLAB),**Python**a powerful and popular object-oriented computer language,**Scientific Python**a set of Python packages for scientific computeing,**Julia**a modern programming language for fast numerical computing,**Jupyter notebooks**,**LaTex**typesetting, a**Gnu-Linux**(unix) terminal, and more. - GeoGebra (https://www.geogebra.org/). Free, downloadable, dynamic geometry software package that is very useful for graphing. Download or use directly on the web. Share constructions with others.
- Octave Free software similar to MATLAB. Runs on Windows, Macintosh, GNU/Linux. Has optional graphical user interface.

CSU Dominguez Hills has a site-license that enables CSU Dominguez Hills faculty and students to download and use **Mathematica** software for free.

*Mathematica*. A comprehensive, professional system for doing mathematics on a computer with excellent documentation, graphics, more. Similar to*CoCalc*, but*Mathematica*is unified by its own language and its documentation is easier to navigate. Students and faculty have unlimited access to*Mathematica*on campus computers, and may may obtain free copies to use at home by following these instructions.- Wolfram Alpha, a
free website for solving math problems and accessing scientific
information hosted by the company that sells
*Mathematica*. CSU Dominguez Hills students and faculty may obtain access to the more powerful**Wolfram Alpha Pro**through the university's site license, following these instructions. - MATLAB Powerful,
comprehensive, professional system for doing mathematics on a
computer, with an emphasis on matrices. Excellent graphics. Widely used in industry, especially in engineering.
**MATLAB**is Prof. Stanoyevitch's favorite. CSU Dominguez Hills has a limited site license that enables students and faculty to use*MATLAB*for free in our computer labs, but students must pay to install*MATLAB*on their home computers or laptops. Students get a big discount on the price, so it costs less than many textbooks.

The Louis Stokes Alliance for Minority Participation (LSAMP) program offers free workshops to supplement selected science and math classes at CSUDH. The workshops are voluntary and are open to ALL science and math students. The program pays for the workshops and pays stipends to students who attend the workshops if they meet certain other conditions.

Workshops generally meet 4 hours per week and are led by a advanced student facilitators. Students work cooperatively in the workshops on challenging material that enhances their performance in class. Experience shows that students who regularly attend workshops score from one- half to one full grade point higher in class than their peers who do not attend workshops. The friendships and contacts with other workshop students that workshop participants develop through their participation help them excel throughout their college years.

- Modern Geometry with Applications: Corrections Errata and corrections for my geometry book.

I was trained in differential geometry, a field that combines geometry with calculus to study shapes in multidimensional spaces, and algebraic geometry, a field that uses abstract algebra to study shapes in multidimensional spaces. Lately my interests are turning toward applied mathematics, a very broad area which focuses on using mathematics to solve "real-world" problems using any mathematical tools that shed light on the problem.

I have taught mathematics at Cal State University Dominguez Hills since fall 1987.

My mathematical interests include algebraic and differential geometry, applied mathematics, and physics. My hobbies include, hiking, gardening, fixing old cars, electronics, and reading. Also I'm trying to learn how to play the piano.

I am married to Dr. Linda Cohen Jennings, professor of economics at UC Irvine. We have two fine sons, Andy and Rob.
