Perhaps you've come across this problem once or twice, or will encounter it in the future: the sheer impossibility to draw a decent equation graph (or even type one) in a conventional text editor, be it as basic as Notepad or as powerful as MS Word. The solution to this difficult situation is FREE Equation Illustrator.
     FREE Equation Illustrator is, in a way, a text editor where text editing capabilities were cut down to a bare minimum, but drawing features far exceed other editors. You can type even the most complicated equations and then illustrate them with ease. There's no separate dialog window for pasting Greek letters, binary operators, arrows and other special symbols: the toolbars at the sides of the application window provide quick and easy access to the symbols.
     You can paste images to FREE Equation Illustrator documents - some popular image formats, such as BMP and JPG, are supported. Probably, the only drawback of this program is that you can't import equations or complete documents to other text-editing applications: once you use it, you have to stick to the program's own file format till you print out your document. Download this free tool now and forget the pain of writing and drawing illustrations for equations in other text editors.
