ExpressionsinBar 2.3 – Powerful computer algebra system in your menu bar

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
