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
