A basic online-only “Home & Hobby” license for Mathematica that does not allow research or commercial use costs $188/year.įor quite a few years now, Wolfram Research, the makers of Mathematica, have provided a free online alternative in the form of Wolfram|Alpha (). And the commercial systems don’t come cheap at all. The disadvantage of using these systems is that one has to interact with them in a specialised programming language which must be learnt first. Computer algebra systemsĪt present the most used general purpose CAS is the commercial system Mathematica but there are other commercial and open-source alternatives as well as specialised software for specific branches of mathematics such as number theory or group theory. Given expressions in terms of algebraic symbols, these computer algebra systems (CAS) can carry out mathematical operations such as differentiation, integration, root finding or simplification and produce a result which is also expressed in the form of symbols. While the idea of doing mathematics on a computer usually brings up images of number-crunching supercomputers, there also exists a long history of using computers to do mathematics not in terms of numbers but in terms of formulae. This will be of interest to learners, students, hobbyists, and anyone keen on using tech tools in their daily lives. The Hindu is introducing a new section called Toolbox, which will explain how to use software and hardware tools for everyday use.
