PocketCAS ( Computer Algebra System – CAS ) offers you quick access to solutions of mathematical problems on your PDA. PocketCAS is a free interface to the open-source Computer Algebra System giac/xcas. xcas enables you to quickly solve complex algebraic problems, e.g. symbolic and numeric integration and derivation of non-trivial functions, solving differential equations etc. It has also a huge support for problems of linear algebra, like solving linear equation systems, multiplying and inverting matrices, finding eigenvalues (and eigenvectors, of course) and much more. If you do statistics or number theory, you will like xcas’ great functionality in those areas, too!
PocketCAS has the option to automatically use the output of xcas to generate beautiful formula images using mimeTeX. Just enter an expression and you will get the result in the same formatting you would find in a mathematical textbook!

PocketCAS contains a fully-customizable, easy to use mathematical keyboard for quick input of most mathematical functions. You can even assign images to displayed on a button rather than mere text! Therefore, PocketCAS is as simple to use as a pocket calculator, but provides you with the functionality of a full-blown CAS – in your pocket, wherever you take your PDA with you!

Missing a function or a macro? Simply add it to the keyboard which is stored in a human-editable XML-file!
