A programmable workpad for mathematics.

This widget lets you evaluate complex mathematical expressions. All results are displayed, and you can use the answer from the previous expression directly. Some other features of this calculator are:
- 2D, 3D and vector graphing.
- Many built-in in functions for trigonometrics, calculus and more.
- Built in mathematical and physical constants.

You can also evaluate javascript in this widget. Not documented in the help right now is how to add custom javascript functions to your math environment. This can be done like this:
js controller.addFunction('f', 'function(x) { return 2*x; }');

Where f is the name of the function.

Update (2008-10-16):
- Ported to mobile.

Update (2008-08-21):
- Added support for ** as power operator in addition to ^ (2**4 == 2^4)
- Added solve function to solve linear and quadratic equations.

Probably the best Maths app. Helped a lot.

It "works" but you are not able to see, what are you typing. If you click on the mathematical symbols (buttons) and after that you write a mathematical expression, the widget give you response. I hope it is a not so difficult to remove this bug. Please do that

Pleaaaase update this wonderful widget so that it works with the newest opera version!

Awesome widget, gets a bit slow during 3D graphing, but other than that works as expected. Kudos to the developer.

Strange, on Opera 11.00 beta, this app doesn't want to be positionned always on top

And it's the only one ! :O

great

Yeah a good substitute for SpeedCrunch ! Maybe it would be my new default calculator

-> it would be create not to be forced to type "ans" to obtain the last result,
-> or maybe add a "ans" button
-> I don't understand how to use the export2()

-> something to solve equation ?!

Great app nevertheless !

Can anyone please help with the vector function of Math Workpad. How does vector(a,b,c...) work? Also, how does sum(array) work? Math Workpad is a very useful widget, but it needs a user manual badly. Would appreciate it if anyone can help with the syntax of these functions. Many thanks.

DG-GeToRiX and BS-Harou Math workpad is now adapted for Opera 10.5 widget runtime and works fine. Please tell us if you will have still any issues.

By skooot , # Apr 28, 2010 6:56:41 AM

DG-GeToRiX: I have the same problem, imho it's because of Opera 10.5x
