Free math expression software for mac

ChocoFlop 0.908 is such a powerful tool which provides users an image manipulation program based entirely on Apple's new CoreImage technology which takes advantages of the processing power in your GPU (graphics card).

This is a preview release of the upcoming ChocoFlop, a graphics manipulation program. As a preview it is entirely free but still unstable and not feature complete.

Main Benefits:

• Small, Launches in a pair of seconds
• Real Time non-destructive filters
• Rich Text Layers
• Load and opens many image formats
• Supports layers, layer masks, selections
• Paint tools with table pressure support
• HDR (128 bits per pixel)
• Universal Binary
• Easy to use for photoshop users
• Can import many additional RAW formats with dcraw

Major features:

1. Non-destructive image editing
   • Chain multiple filters without applying them: modify them or remove them when you want
   • Rotate and scale your layers without applying the transformation on the pixels: zero loss of quality.
   • Unlimited layers and sub-folders
   • Layer masks, even for dynamic filters
   • Built-in HDR support (High Dynamic Range).
2. Filters and tools designed to take advantage of your graphics card's power
   • Dozens of filters included, more with standard CoreImage plugins.
   • Mix your layers with all industry standard blending modes and more.
   • All the tools you can need to either retouch or create.
3. File Formats and save for web
   • Load and save to dozens of formats.
   • Import RAW images, including rare formats thanks to dcraw.
   • Export to Jpeg, PNG, or GIF and obtain the smallest possible sizes.
   • Fine tune exportation with a real time preview (quality, colors, strip information)
4. Rich Text Layers and PDF/AI layers
   • Rich Text with all imaginable attributes : change fonts, colors, alignment, spacing... basically anything TextEdit can do.
   • Stored as simple RTF files for easy import/export.
   • Text can be affected by non-destructive filters, just like any other layer. You can for example apply a Perspective filter on a text and then edit this text and see the perspective update in real-time.
   • Import PDF and Adobe Illustrator (.ai) files as layers
5. A good mac citizen
   • ChocoFlop is a native mac application: this means there's no slow compatibility or portability code around. It's made for mac only. The application download file is only about two megabytes.
   • ChocoFlop can generate both preview and thumbnail images for in QuickLook (requires OSX 10.5 Leopard).
   • Spotlight plugin to efficiently tag and search your images (currently in development)
6. Advanced yet familiar GUI
   • Full Screen mode.
   • Real Time Preview for all filters and transformations.
   • Type simple math expression in the inspector
   • Industry standard shortcuts and user interface.
   • Easy transition from much more expensive packages.

• Mac Intel or PowerPC G4.
• Mac OS X 10.4 or higher.

Mathomatic is a free software, published under the GNU Lesser General Public License (LGPL version 2.1). This is a console mode application that does quick calculations and symbolic math.
Mathomatic is designed to be as general and easy to use as possible, and as such, has no programming capability.
Mathomatic implements most of the rules of algebra for subtraction (-), addition ( ), modulo division (%), multiplication (*), division (/), and all forms of exponentiation (^). All arithmetic is double precision floating point with up to 14 decimal digit
Mathomatic compiles and runs under any operating system with a C compiler, especially GNU/Linux. There are no dependencies other than the standard C libraries.
Mathomatic has been under development since 1986 and now stands at 16,000 lines of code (including comments).

Main features:
- combine and solve algebraic equations,
- completely simplify, expand, and compare expressions,
- do calculus transformations (derivative, polynomial integral and Laplace, extrema, and Taylor series),
- help with series analysis (sum and product),
- do standard, complex number, and polynomial arithmetic,
- generate efficient C, Java, and Python code from equations,
- and perform quick calculations, all in color, for easier reading.

Enhancements
- "primes/mult" improved and renamed to "primes/matho-mult", so you can install as a unique program, if you wish. "primorial 1" works now, too. Roots command enabled in the symbolic math library.
- Fixed factor command parameter handling and results, it was not user friendly. Also fixed factor command for consistent behavior in the symbolic math library.
- Allow separate install of Mathomatic binaries and documentation in makefile.

This free Yahoo! widget tries to show you the beauty of mathematics, more precisely the beauty of Platonic solids. You can choose between the five Platonic solids tetrahedron, hexahedron, octahedron, dodecahedron and icosahedron as well as set a few animation parameters.
