Math workpad
A programmable workpad for mathematics.
Description
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.

"a beautiful mind" oh, mathematics...
Hi man, it really looks great, but i have had some troubles trying to make anything, whatever, i mean i only have seen the first message "If this is your first time, type help introduction" and I haven't been able to do something, please help me, I have others widgets some of them work very well, some others like this one does not. I'd like read any suggestion.
DG-GeToRiX: I have the same problem, imho it's because of Opera 10.5x . I hope they will fix this one soon
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.
You can not conquer the world without math...
Love it, very useful for me. 5★
Amazing widget but it will take me time to master it.

impossible download on opera mobile 10
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.
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 !
great
Strange, on Opera 11.00 beta, this app doesn't want to be positionned always on top And it's the only one ! :O
does not work in opera 11.01
my phone is nokia 5230
Awesome widget, gets a bit slow during 3D graphing, but other than that works as expected. Kudos to the developer.
Pleaaaase update this wonderful widget so that it works with the newest opera version!
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 )
Probably the best Maths app. Helped a lot.
