Sage Seminar . . .

The seminar is scheduled for March 19, 2019, in room 3410. The updated seminar schedule will be published here once known.
  • A guidebook for ECC students. It is a basic tutorial, and I will cover how it should be used during the presentation.
  • Some projects to consider doing if you finished the tutorial in the guidebook. Again, I will present how this document should be used during the presentation.
These documents are in draft mode, and updates will be made frequently. If you see an error, I would appreciate your letting me know.

These additional resources may prove helpful.
  • Gregory Bard's website has a free book on using Sage. It is worth taking a look at!
  • Another excellent, and free Sage textbook, is Computational Mathematics with SageMath. I suggest watching my video on how to read a textbook first!
  • David Joyner and William Granville published a free book on using Sage for differential calculus. Again, it is worth taking a look!
  • Sean Mauch has a rather lengthy tome on Applied Mathematics, and it's free to download. Free does not always mean useless, and in this case, this free book may cause you a lifetime of thought.

Cheat Sheets . . .

These may be a little dated, but at least they'll get you started on the possibilities.

An introduction to Sage

Quite simply, Sage is software that will allow you to explore many aspects of mathematics, including algebra, calculus, linear algebra, combinatorics, numerical mathematics, arbitrary precision arithmetic, number theory, statistics, stochastic models, and much more.

Fortunately for us, Sage is free to use and is available from as a free download. The founder and developers of Sage have a simple mission: "Creating a viable free open source alternative to Magma, Maple, Mathematica, and Matlab." It does that, and probably more importantly, it may provide a basis for you to become involved in a rich tradition of intellectual sharing inherent to any scientific discipline, mathematics notwithstanding. Unlike proprietary software, you have complete access to the source, and that's important. Not only can you look at the source code of Sage, but you can contribute to its growth by becoming a part of the Sage community of coders and users. Yes, just like any scientific endeavor, it requires a community to grow, and I am hoping that some of you will prosper in this very vibrant community.

The originator of the Sage project, William Stein, is a mathematician at the University of Washington. He, along with many others, is intimately involved in making sure Sage remains open and free. Mathematics is open and free too---that is, the theorems of mathematics are shared and then vetted by many, and similarly, Sage is too. You may not be interested in the backend of mathematics, that is, the theorems, but they're there if you want to look at them. You may also not be interested in your software's backend either, few are, but open-source software is important because it has no secrets. Mathematics is not magic, and neither should your software!

Sage uses the Python programming language, supporting procedural, functional, and object-oriented constructs. Working knowledge of Python is helpful when working with Sage but is not required to start. Some knowledge of functional programming is desired, but Sage, like Python, can easily be used at the introductory level. As your skill-set with Sage develops, you may desire to install Sage on your personal machines. However, the materials in the tutorial sections of the guidebook can be done immediately by visiting Like most journeys worth taking, I suggest you take the time to explore beyond what is presented in this brief introduction. If you're really perplexed, you may decide to stop by Ron Bannon's office to get a demo of what you can do. But again, you need to try and explore Sage by yourself. As in life, it is not enough to watch, so please continue to read on!

Ad Infinitum . . .

A lot of prior work went into promoting Mathematica here at ECC.

Here's a page that almost no one will remember:

Here's a course that only a few students will remember:

We've also spent a fortune on maintaining a license that virtually no one used.

Sage is free, and now I have spent a load of time on this too. It may not be for you, but a student leaving our program should know the software used professionally. Minimally, a mathematics student leaving ECC should at least know basic LaTeX, Sage, and Python. I think some of you would be shocked to see what other schools expect, let alone industry!
