Aside from using Maxima for symbolic integration, I belive Sage uses Pari for highly optimised polynomial arithmatic, and I have used Sage for some pretty intense linear algebra computations (over the integers as well as over finite fields), although for this kind of thing you'll probably not want to rely on the online server which can be a little slow.Īnd let's not forget that you also get the moral boost of being part of something really positive-an movement to create an open source alternative to costly and "closed" alternatives like Mathematica, Maple and Matlab. Last updated on: 01:33 UTC Metadata for speedcrunch in universe. Exact or approximate: sqrt(32) returns 4 sqrt(2) or 5. Although Sage is based on Python (so in particular any Python syntax will work), you really don't need to know Python to get started using Sage-I didn't when I started. RPN mode Result display: Supports all common number bases, as well as negative and non-integer radices, sexagesimal numbers, time format, and roman numerals Many customization options: precision, max/min decimals, complex form, multiplication sign, etc. I used the online notebook for around 6 months before I installed a copy on my own computer, and this was because I became interested in developing Sage. (I just googled "sage notebook screenshot.") It's been designed to look and work like the Mathematica notebook system, and it's surprisingly slick and easy to use. Some distinctive features are auto-completion of functions and variables, a formula book, and quick insertion of constants from various fields of knowledge. It features a syntax-highlighted scrollable display and is designed to be fully used via keyboard. There is also an alphabetical list of all functions. They are documented in this reference, organized by categories. Here's a screenshot of what the notebook looks like. SpeedCrunch is a high-precision scientific desktop calculator. SpeedCrunch includes a large number of built-in math functions and constants. This is a very popular option-I believe that in the last 9 months around 30,000 people have created accounts! It's perfectly suited for high school students and undergraduates, since no installation is necessary, and hence it can be used straight away in any computer lab with internet access. I think this is really nice-it feels like it's your "gmail" but for maths, so you can just log in from anywhere and "check your maths" if you want :-D This is true, the binary downolad comes in at around 1 gig, however you can use it for free online, without having to install a thing! Head on over to, and sign up for a free account, which will allow you to create and save your own worksheets. SpeedCrunch is a free, fast, high precision open source algebraic calculator. Firstly someone mentioned that Sage is quite large to install. rpn basen, hex, octal and binary modes scientific/engineering functions. If your on the Windows Platform there is also a free desktop version eCalc with basic functions.A few people have mentioned Sage, but I think deserves a bit more of a plug. The app also comes with Six math help PDF documents, which can be referred for the formulae of Base converter (decimal, octal, hexidecimal, binary).Complex number support in rectangular and polar forms.Both the talking calculator and the paper tape will work with the alternate calculators as well, which can come in handy to keep track of what data you’re working with. Factorial, remainder, inverse, power, and logarithmic functions Calculator RPN Mode can be accessed by hitting Command+R or by enabling it from the View menu.ConvertBot – iPhone Unit Converter With Support To Over 520 Units and 100+ CurrenciesĮCalc also available as a iPhone or iPod Touch app, which costs $4.99 but the number of calculations it performs it completely eliminates the need of a handheld scientific calculator.Here’s a list of functions that the iPhone/iPod Touch can perform :.You can quickly copy the last calculation result to the clipboard using Ctrl+R. The result is shown in the scrollable display. SpeedCrunch is easy to use, just type the expression that you want to calculate and press Enter. SpeedCrunch – Portable Scientific Math Calculator SpeedCrunch is a fast, high precision and powerful open source desktop calculator.eCalc has 2 input modes Algebraic and RPN Mode, It also stores the results of the past calculations in a stack and can be accessed by scrolling up and down. It also has the functions of a basic calculator.It supports complex calculations like Unit Conversion, Equation Solver, Base Conversion, Constants also. If the Windows Calculator does not suffice your needs, here a Scientific Calculator called eCalc – Scientific Calculator which can be accessed right from your browser without the need of any plugins.
