Description
ExpressionsinBar is a simple menubar application which provides powerful computeraided 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's the perfect app for teachers, math students, scientists, and the geek among us!
• A GORGEOUS OUTPUT
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. Mathematical expressions are presented in highresolution PDF form that can be pasted into your Documents or Presentations!
• A VERY SIMPLE USER INTERFACE
 Click the Menubar icon and ExpressionsinBar pops open an input expression box. Enter the expression, view the result.
 Beautiful output easily copied into text editors such as Apple Pages or Microsoft Word, or presentation programs such as Apple Keynote or Microsoft PowerPoint.
 Alternatively export the result of a computation in LaTeX syntax to TeX processors, such as TeXShop or TeXworks.
 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"
• KEY MATHEMATICAL 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

 Access to several fundamental constants of nature such as the speedoflight, Planck constant, the elementary electric charge, etc.
• RENDER USING LaTeX SYNTAX FOR GORGEOUS TYPESETTING
 "//"and "@" features to interpret input with LaTeX text or math mode syntax
 Flexible and easy way to format equations
 Use it to write chemical reactions (such as @NaOH+HCl \rightarrow NaCl+H_2O)
• USER REVIEWS
“Educational, provide a fun way to learn about mathematics, yet are tremendously useful to any user who needs a quick way to dig up specific math expressions onthefly.”
