Rapid-Pi is an add-on for Microsoft Word (and other countersign processors) that will transform the direction you participate mathematical formulae, equations and expressions into documents. Rapid-Pi was designed with a single purpose in heed - to spare you time when editing math in documents. Rapid-Pi's text-based input is a just faster direction to input math. Most equation editing programs compel you to pawl on toolbar buttons or go through menus in decree to introduce symbols and expressions. This process is inherently slow and painful. Even simple things comparable fractions take up too much time - you have to pawl on the fraction button, then pawl in the numerator, type the numerator, pawl in the denominator and type the denominator. Consider how much faster and easier it would be if you could just type "1 / 4". That's exactly what you can do with Rapid-Pi. NOTE: Rapid-Pi is an add-on for your existing countersign processor application (comparable Microsoft Word), not a stand-alone syllabus. This means that you will continue to usage your favourite countersign processor, inserting Rapid-Pi equations into your document whenever you take to participate math. Inserting a Rapid-Pi equation is easily - scarcely pawl on the Rapid-Pi button on Microsoft Word's toolbar (toolbar button is currently only provided for Microsoft Word 2000 and later). Rapid-Pi supports a macroscopic number of mathematical symbols and expressions, including all symbols supported by Microsoft Equation Editor. If you don't hump the keyword for a symbol, you scarcely pawl on the appropriate toolbar button and Rapid-Pi will introduce the text for you (for example, ".a" for lower-case alpha, ".int" for integral, etc). Soon, you'll probably find that you don't take to usage the toolbar 90% of time. The toolbar will still be available for the occasions when you take to participate a symbol that you've never used before (or if you forget how to participate a rarely-used symbol).
