wats up ya'll.. this program is quite efficient the only problem is the log is really natural log as in to base e and not 10. Also that the trigs are in radians no option of switching to degrees. And for anyone who has problems with the plotting feature, firstly you have to evaluate the function in one statement then you go to the list feature then select new the make enter your plotting parameters but place the letter of your function instead of the full function. So for eg your function was f(x)=x^2 then you enter 'f' into your plotting parameter.. Hope this helps =D

Difficult to operate on a mobile without a QWERTY keyboard, but works as advertised. Integrated help is quite useful.

THE BEST!!! this application rulez :D clear and easy syntax no silly button menus etc. plain and simple but extremely powerful. the only feature i missed was a kind of command completion, cause typing on a mobile phone is hell slow especially with all these parentheses and commas etc. but besides this app is amazing and very flexible please keep on developing and adding even more features!

I like my mobile phone because it is exactly a phone and I am in no mood to change it!Anyway,if there is something enhancing its issues,it's warmly welcome!This program is very good!

It`s great the infix notation! RPN logic and old HPs really suck!

For [3/10 on May 11, 2005] OlEG:
If you need also the `lg` function (AKA log in base 10) just define:
lg(x)=0.4342944819*log(x)

How to run it on Nokia6230i, plzzzzz, help someone :)

Amazing program. Runs great

The best calculator I`ve ever seen for a mobile. To get the plot right I also needed the help from further below. With the keyboard of the 6820 it is also extremely easy to write functions etc.
Great!

The Software works beautifully with my excerpt for one thing, after it has been running on my phone for some time it just jams, I can`t open it or run it. Could you add more function with are more user friendly. And increase the equaation storage space to enable more function storage

It is very useful but not that user friendly, as well... it took me a bit to understand how to plot, `cause I was writing all instructions at once, without striking evaluate between them...
VERY GOOD, anyways !
