ExpressionsinBar 2.2

Simple menubar application which provides powerful computer-aided algebra computations.

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 (?, 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
