ExpressionsinBar

ExpressionsinBar is a simple menubar application which provides powerful computer-aided algebra computations. It's a powerful tool for evaluating mathematical expressions that lives in the menubar of your Mac ! So it is always just click away ! It can do numerical calculations - It can also do symbolic math ! Equations can be output in a PDF form that can be pasted into your Documents or Presentations ! It's the perfect app for teachers, math students, scientists, and the geek among us ! • Unlike most other Equation Editors, ExpressionsinBar helps you resolve the math and then prepares a neat output for an easy insertion in your documents or presentations. • How to use: Click the Menubar icon and ExpressionsinBar pops open an input expression box. Enter the expression, view the result. 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. Alternatively export the result of a computation in LaTeX syntax to TeX processors, such as TeXShop or TeXworks. • Key features: - 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 - 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 - Units in operations - Conversion of units, transformation to SI units, simplification of units - Access to several fundamental constants of nature • Extended user interface and keyboard features - Scrolling panels with easy to use functions - Menu with variables, functions, syntax and tips - Use keyboard arrows to navigate function arguments - Easily select to render "input only", "input =", "result" and "input and result" • Render using LaTeX syntax for fastest type-setting - "@" feature to interpret input with LaTeX syntax - Flexible and easy way to format equations - Use it to write chemical reactions (such as @NaOH+HCl rightarrow NaCl+H_2O) • A simple User Interface - Display short "howto" when typing - Automatic completion of functions when typing - Zoom slider • Services integration - access the powerful tools within other applications, such as Word or Textedit - Replace Selection by Result - Replace Selection by Result in LaTeX format - Replace Selection by Image of Result • Support for OS X 10.8 and beyond +++ Thank you to everyone for your cool comments and suggestions ! We are working on each one of them. +++
