- Sage A free computer algebra system, with many of the capabilities of Mathematica, MATLAB, and Maple. Combines many mathematical programs (Maxima, GAP, Pari, Octave, etc.) in one package with a common interface. (Prof. Pong's favorite). A direct link to the cloud server is https://cloud.sagemath.com.
- GeoGebra a free, downloadable, dynamic geometry software package that is very useful for graphing. Available at http://www.geogebra.org/cms/
- Octave Free software similar to MATLAB.
- FreeMat Another free software similar to MATLAB, recommended by Prof. Stanoyevitch. It runs on Macintosh, Windows, and Linux.
- Scilab Yet another free software similar to MATLAB. Includes Scicos toolbox similar to Matlab's Simulink. Maintained in France, but English documentation is available.

The student versions of these packages have all the power of the professional versions, but at an affordable price. Our campus has site licenses for these systems so you can run them in the computer labs for free.

*Mathematica*. A comprehensive, professional system for doing mathematics on a computer with excellent documentation, graphics, more. (My personal favorite.) Students and faculty have unlimited access to*Mathematica*on campus computers. Faculty may obtain free copies to use at home.- Wolfram Alpha, a
free website for solving math problems and accessing scientific
information hosted by the company that sells
*Mathematica*. - MATLAB A comprehensive, professional system for doing mathematics on a computer, with an emphasis on matrices. (Prof. Stanoyevitch's favorite.)

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.
