## PocketCAS – a new computer algebra system for the iPhone

There’s a new CAS in town and this one runs on the iPhone! PocketCAS is the brainchild of Daniel Alm and is based on the powerful open source computer algebra system, XCas.  Functionality includes symbolic calculus, linear algebra, the numerical solution of equations and more – click here to see a more detailed list.

It currently lacks any support for graphics but Daniel tells me that he has plans for the inclusion of both 2 and 3D plotting in the future.  At the time of writing it is selling for just $4.99 which seems a bit of a bargain to me and so much more useful than the 1001 tip calculators that you can find for the iPhone. I haven’t been able to try it out myself since I don’t have either an iPhone or an iPod touch and, unfortunately for me, Daniel has no plans for an Android version. However, if these screen shots are anything to go by, it is well worth your time and I would be interested to hear the opinion of anyone who has bought it. 1. Oh dear. Proctoring freshman math exams has gotten a little harder. 2. It’s on sale this week!$0.99 due to the version update.

3. Seems good, knows much, but it is extremely hard to use, and sometimes can not solve surprisingly simple problems. Better to use the free online version of Wolfram Alpha. You can also try “Symbolic Calculator” which also has problems, but at least can plot.
