Conic Sections and Dandelin's Conics notes from a talk given in Serban's TOES teaching seminar, Friday, Apr. 20, 2018.
I'm not teaching during spring 2018. I'll return in the fall.

Links to Math Software
Open Source software (free)
- 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.
Commercial Software that is Free to Dominguez Hills Faculty and Students
CSU Dominguez Hills has a site-license that enables CSU Dominguez Hills faculty and students to download and use Mathematica software for free.
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.

Dr. Jennings' mathematical interests
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

Hills since fall 1987.

Interests and Family:
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.
