GraphCalc is described as 'All-in-one solution to everything from everyday arithmetic to statistical analysis, from betas to Booleans, from cubes to calculus, from decimals to derivatives. GraphCalc combines all the features of a professional mathematics package with the simplicity of an' and is a Calculator in the education & reference category. There are more than 25 alternatives to GraphCalc for a variety of platforms, including Windows, Mac, Web-based, Linux and iPhone apps. The best GraphCalc alternative is Wolfram Alpha, which is free. Other great apps like GraphCalc are Qalculate!, Mathematica, Matplotlib and GnuPlot.
Wolfram Alpha is a "Computational Knowledge Engine" - different from a search engine, it answers factual queries directly by computing the answer from structured data, rather than providing a list of documents or web pages that might contain the answer.
