Portable Derive 6

Derive 6 is a powerful system for doing symbolic and numeric mathematics on your PC.

It processes algebraic variables, expressions, equations, functions, vectors, matrices and Boolean expressions like a scientific calculator processes numbers. It's useful from KS3 to University and beyond.


Problems in the fields of arithmetic, algebra, trigonometry, calculus, linear algebra, and propositional calculus can be solved with the click of the mouse. Make plots of mathematical expressions in two and three dimensions using various coordinate systems. By its seamless integration of numeric, algebraic and graphic capabilities, Derive makes an excellent tool for learning, teaching and doing mathematics.

Derive is easy to use but very powerful and accurate. Floating toolbars give quick access to Greek and other mathematical symbols.

Verify results and explore different approaches to problems.

Derive 6 now shows intermediate steps in calculation.
