The Mars Climate Orbiter made headlines back in 1999 when it approached Mars on a trajectory bringing it too close to the planet and wound up either destroyed in the Mars atmosphere or orbiting the Sun.

If you don't mind the lack of a built-in graphical interface and you're OK with "computerish" notation, a great completely free option is the Python programming language.Numerous open-source software packages now provide engineering math capabilities and go easy on the pocketbook. You don't have to learn any programming per se to use the interactive interpreter as a scientific calculator with fraction support. You do have to import various modules that are included in the standard library, such as fractions for fraction support decimal for exact decimals and math, cmath, or statistics for functions beyond simple arithmetic. Without importing anything, you get basic arithmetic with either fixed-precision floating point numbers (IEEE 64-bit floats) or arbitrary-precision integers.

You can easily download free third-party packages for even more sophisticated functions as well as graphical visualization.

I like using a programming language interpreter for calculations in part because it's easy to assign names to intermediate results (much more powerful than a normal calculator's memory functions), it's easy to repeat and edit input that I've mistyped, and it's easy to write my own customized functions that aren't included with any existing calculator. That last part is heading into real computer programming, which is there if you want it, but which you can ignore if you don't need it. Some kinds of academic software is flexible enough to handle engineering simulations.It is relatively easy to find math packages devised for college coursework and research that can be repurposed to do meaningful tasks in engineering.The > is Python's prompt where you type things in. When math professors get frustrated, the result can sometimes be mathematical-analysis software that is free for the asking. Picture this: The instructor of a calculus or higher-level math class realizes that students would benefit greatly from access to mathematical-analysis software.

But commercial packages are too expensive for every student to have a copy. So the professor sets out to create a math package to be used as free course material. The resulting software becomes open source, and the rest is history. The above scenario has played out several times over the past few years. Free math packages that include Octave, Sage, and Ptolemy II, as well as several others, began as classroom aids, then were expanded either by their original authors and collaborators or by independent contributors who took advantage of the open-source nature of these packages. The point of these packages is to mimic the environment of commercial packages, often the Matlab package from MathWorks, Natick, Mass. For example, consider GNU Octave, a high-level language for numerical computations now used by thousands of people worldwide. Entering data in a command line lets the user solve linear and nonlinear problems numerically, using a language that is mostly compatible with Matlab. It can solve common numerical linear-algebra problems, find the roots of nonlinear equations, integrate ordinary functions, manipulate polynomials, and integrate ordinary differential and differential-algebraic equations.

Octave authors say they originally set out to create specialized tools for solving chemical-reactor design problems but eventually realized that approach was limited and opted to create something more flexible. Over the years, other packages have been developed that augment Octave’s capabilities. It is built out of nearly 100 open-source packages and can be used for basic algebra, calculus, elementary to very-advanced number theory, cryptography, numerical computation, commutative algebra, group theory, combinatorics, graph theory, exact linear algebra, and more.įor example, one called pMatlab enables parallel programming by providing distributed arrays and functions.Īnother package that began life in academia is called Sage. The user interface is a notebook in a Web browser or a command line. Using the notebook, Sage connects to a Sage server on the network. Inside the Sage notebook users can create embedded graphics, mathematical expressions, add and delete input, and share work across the network.
