Why use Formula Calculator?

Formula Calculator does not imitate a pocket calculator - instead the mathematical expressions are typed in directly and the results are evaluated as you type. The entire mathematical expressions are there to see, making it easier to spot mistakes.

Very long calculations can be broken into smaller calculations. You assign names to intermediate results, just as you would in algebra or arithmetic. You can open multiple worksheets at any time.

Formula Calculator comes with the mathematical functions that you find on a scientific calculator and you can define your own functions, simply by typing them in. More advanced functions enable numerical differentiation, integration, finding complex roots (zeroes) of functions, Fourier transforms, fitting functions to data. You can define your own constants and save them for use in any arithmetic expression - this is very useful for constants that you use often, such as the gas constant, Avogadro's number, Planck's constant, and so on.

Formula calculator allows you to easily graph your functions, ideal for students who want to understand what functions look like and how they behave when parameters are varied. You can format the graphs how you like, including labels and colors and output them as images, pdf files or in eps format for inclusion in reports.
