From Trident Software:

Rapid-Pi is an equation editor for Microsoft Word that provides a faster way to edit math in documents. Rapid-Pi allows you to enter mathematical expressions as easy-to-understand text. For example, you can type (y+2)/x^2 to create a fraction with y + 2 in the numerator and x-squared in the denominator. Rapid-Pi was designed with a single purpose in mind - to save you time when editing mathematical formulas, equations, and expressions in documents. Rapid-Pi is an add-on for your existing word processor application (like Microsoft Word), not a stand-alone program. This means that you will continue to use your favorite word processor, inserting Rapid-Pi equations into your document whenever you need to enter math. Inserting a Rapid-Pi equation is easy - just click on the Rapid-Pi button on Microsoft Word's toolbar.

Version 2.01 features integration with Excel, PowerPoint, Publisher along with Compatibility Mode rendering.

From Runiter:

Easy-to-use math calculator that immediately computes the result as you type a math expression. It allows to calculate multiple math expressions at the same time. It also allows defining your own variables and functions that can be set to a value or other math expressions. It has a beautiful user-interface that conveniently allows you to directly edit the expression or if you prefer use the visual key pad to enter new expressions. There is support for over 20 math functions.

Version 1.5 adds support for defining custom functions that call themselves (recursive functions) and support for true/false expressions.

From Runiter:

Graphing equations, 2D or 3D, is easy with this graphing calculator. Simply type down the desired equation and click on the draw button (eg. y=sin(x)+3x or 5x=sin(xy)+y) and let our advanced graphing calculator take care of the rest. 3D graphing can be achieved by simply introducing a z variable in the equation. There are tools included in the graphing calculator for slopes, area under curve, matrix transformation.

Version 5.8 has ability to save and reopen axis and draw properties as well as the equations, ability to plot polygons from a list of points, and has several enhancements and bugs fixed.
