1. What’s iMathGeo ??

News

 iMathGeo is a software I began to develop when I was a student in math.

 At the beginning, It was only to simplify my teacher’s life in maths. The first goal was to have the best solution to write as faster as possible mathematic text.

 I develop this software in many ways:

• formal calculation
• graphics
• basic differentiel calculus.
• export/import to others softwares

2. What’s new in the 2.6.0 version

• New analysis functions :
  • Canonical form
  • zeros for Real and complex numbers.
• New statisticals functions
  • Randomize, median, quartiles, linear regression, power regression, polynomial regression, logistic regression.
• Laws :
  • Bernoulli law
  • Binomial law
  • Chi square law
  • Normal law
  • poisson law
  • Student law
• The "ANS" mechanism is now implemented.
• New scrollbars for Lion.
• Many bug correction with OS X 10.7.2.
• A bug correction with the "derivative" function.
• A bug correction with the "integrate" function.
• A bug correction with the mechanism of close or open the document.
• Now you can auto save your documents
• Solve function improvment
• Menu scripts improvements.
• A new QuickLook module
• OpenOffice 3.3 and LibreOffice 3.3 support
• word 2011 support
• The Roman charset is now supported :

 New functionalities

• working with big numbers.
• Arithmetic is now supported (isprime, ifactor algorithm,Bezout, pgcd, div, modulo, etc...)
• enter your mathematical formulas and transform them so that they are to simplify to the maximum.
• make symbolic algebraic calculation.
• make substitutions.
• it’s possible to draw integral functions .
• the thread management is totally rewritten.
• growl is totally supported.
• through services, it’s possible to do computation under other software like "Numbers", "Pages", etc ...
• differential calculation.
• make factorizations.

• substitution with the "Eval" function.
• solving equations and inequation
• working with matrices (eigen vectors search, inverse a symbolic matrix, etc....).
• Statistics (with mean, correlation, variance, etc ....)
• Snow Leopard support OS 10.6
• Now it’s possible to draw the Gamma et Zeta function
• It’s possible to use Growl small notifications
• The copy and paste is now under Snow Leopard with PDF format
• The script Menu is now useable under Snow Leopard
• support of Pages/Keynote/Iweb etc … under Snow Leopard.
• Trigonometric mode support (radian, degree, gradient).
• Applescript support (for the roll and rolld functions)
• the fsolve function now work correctly with bisectionsolver option.
• The matrices work now fine with applescript.
• The software is now more stable with many tasks running together
• Now the memory and the processing time is freed correctly when a task is killed.
• finding primitive and integral.
• solving linear or non linear equation.
• finding roots in C or R algebra
• finding limits.
• factorization
• Taylor developpement.
• finding infinits sum or products.
• working with matrices (inverse, transpose, eigen vectors search etc...).
• automatic completion in each text field.
• A better support for superscripting with the new function eval.
• Many new functionnalities in typographical way (equivallement, union, intersection, etc...)
• It’s possible now to insert images directly on your document :

 iMathGeo can now be used like a presentation tool.
 It works now in full screen mode.

iMathGeo is now compatible with OpenOffice 3.0 Indesign CS4 and TeXShop through the communication inspector.

• Now you can directly change the aspect of the document without opening the color or the font palette.
• It’s possible now to add, divide (etc ...)the last two lines.
• It’s possible to apply a shadow to the text, it’s useful in the case of a white font.
• The substitution process is totally rewritten, now it’s possible to do basic superscripting, like a:=3/2.
• The Applescript management is rewritten too.
All elements are objects, who have properties (matrices, 2D/3D graphics, titles, variables, etc...).
The document is now scriptable too with the font management, color etc...
• You can export a line through Applescript.
• You can export all the document to a LaTeX or a pdf file..
• You can export each lines to a specified image format (tiff/jpeg, etc...) trough the contextual menu. It’s always possible with litteral expression too.
• It’s possible to add/substract lines.
• It’s possible to manage subscript.
• It’s possible to add in the document some titles. It’s useful to find rapidly some information in the document.
• Now it’s possible through Applescript to do dynamic geometry.
• Now I add a spotlight plug-in. Now it’s easy to find expressions in your documents
• I add too a quickLook plug-in.

 Typograficall adds

• Now the engine manage the spaces between each caracters.
• Now it’s possible to manage all the fonts and you can use them with all the classical operators.
• I add new operators, like approximately, different ....
• Now it’s possible to manage matrices
• It’s possible to manage new symbols, the symbols Real, Complex, Natural, etc ...
• It’s possible to write such expression : AB’+BC’ or f’(x) etc....
• Now it’s possible to use the the underscore symbol.
• It’s possible to use the °,* symbol.
• It’s time to use the integral an sum symbol too.
• It’s always possible to use the, angle, arc and vector symbol too.
• It’s possible to write from two manners a differential.

 The communication is improved

• The communication inspector is rewritten, it’s possible to personnalize all the the inspector
• Word 2008 SP1 is now supported. But if the document is to long, you’ll notice some problems of performance, it’s a problem of word.
• Now Indesign CS3 is totally supported, you can manage all the fonts.

 Bugs

• Many bugs corrections, the performance are better and the memory management too.

 With the Graphic

Drag transparent graphics

• the 3D engine is optimized for cocoa.
• It’s possible to have a transparent background for all the graphics.
• to add some squaring to the 2D graph and to change the color of the curve and the axes.

 iMathGeo has now a customizable toolbar.

 all the multitasking architecture is rewritten too.

 The importation and the exportation/Importation are better than before :

• Indesign CS3 is supprted and CS2 too
• iWork 08 (Pages, Keynote, Numbers)
• iWeb 2/iWeb 1
• and always Word VX and Word 2004.

Some bugs correction...
