Powerful computer algebra system in your menu bar.

What is ExpressionsinBar for Mac

ExpressionsinBar is a simple menubar application which provides powerful computer-aided algebra computations. A mathematical expression entered in the popup window is immediately computed and the result is displayed in an associated subview window. With the drag-and-drop feature, results are easily copied into text editors such as Pages or Microsoft Word, or presentation programs such as Keynote or Microsoft PowerPoint. The algebra functionalities include:

  • Constants (π, e, etc.)
  • Integers, fractions, floating numbers
  • Sequences, lists, vectors, matrices, strings
  • Operators (+, -, *, /, ^)
  • Arithmetics on integers, rational, and floating numbers
  • Arbitrary precision arithmetic, operating on signed integers, rational numbers, and floating point numbers (no practical limit to the precision except by the available memory)
  • Operations on fractions (integer and fractional parts, numerator, denominator, simplification, continued fraction expansion of real)
  • Real functions (max, min, round, floor, sign, frac, ceil)
  • Complex functions (re, im, abs, conj, arg, affix)
  • Polynomials
  • Factorial, binomial
  • Exponential, logarithms, roots, powers
  • Trigonometric functions, hyperbolic functions, and inverses
  • Algebraic transformations (simplify, normal form, expand, factor)
  • Trigonometric transformations
  • Probabilities
  • Statistics (1d and 2d)
  • Polynomials algebra
  • Algebraic calculus
  • Numerical calculus
  • Derivatives, limits and series expansion, integrals
  • Equations, ordinary differential equations

Version: 0.6.1
I use version 0.1, which is already quite cool (and was free). The underlying formal math "motor" behind it is the open source XCAS development, , whis does has an OSX implementation, but not as a fast menu item ;-) Indeed I'm considering paying now.

Version: 0.1.0
Dev link on this page seems dead, though finds the site. System requirements seem to be 10.7+, not 10.6+ as shown on MU. In any case, does not work for me on 10.6.8. Shame, looks interesting.
