Some Minor Bug fixes

Display issues on 1.5
There were a lot of display issues for Cupcake users.  Cupcake is basically not compatible with a lot of things. About 80% of the work I do addressing compatibility relates to Cupcake. This is a continuous issue for many developers, and I apologize to the users for the problems.  Things should be pretty much fixed for the time being.  If I overlook anything again, please let me know this is going on.

Calculus Tools 0.8.9

Chinese Localization!!!

Thanks to everyone at goapk.com for this!

Calculus Tools 0.8.8

Fixed a bunch of issues with functions not saving.

Thanks Roland!

You can now add the derivative to the graph.

Linear Algebra Suite

I have begun working on a Linear Algebra suite for Android. I am not sure yet whether this will be included within the Calculus Tools application or released as a separate application. I imagine a beta version will be ready within a week. If anyone has any interest in testing this out before release, send me an email, and I will deliver the application to you as soon as a beta build is available. Also, any suggestions of features would be greatly appreciated.

Calculus Tools 0.8.7

Fixed tan not working properly on keyboard.

Thanks Sam!

On a side note, we breached 4k downloads today : )

Installing on your SD card

I have allowed this program to be installed on your SD card in Froyo, and of course you can install it on the SD card using Apps2SD. I have done this primarily because I know the file size is somewhat large ~1 MB, and I know this has been a complaint with many apps on the Market not updating to accommodate this. I would however like to give anyone a word of caution that chooses to do this. It is not always the best idea to install applications with services (like the bundled math keyboard) on your SD card. When you mount or remove the SD card, the keyboard will be killed, and it must be re-enabled in your settings upon returning the SD card to the device. If you find this to be a pain, I recommend you leave the application on your internal storage.

Calculus Tools 0.8.6

New Icon!!

Thanks to Jonathan Thompson for designing this.

Also, I fixed a number of bug that were rather trivial.

Calculus Tools 0.8.5

Redesigned methods for saving functions - I felt that the old method was sort of cumbersome and not entire useful. From now on all functions will be saved in the graph functions database. This also allows the functions in the graph to be saved across different sessions. The function list will now allow you to leave invalid functions saved in it, but they will not be graphed.

Surface area is now able to be found for functions of 2 variables. This, like the double integral (which uses the same method), can sometimes be rather slow.

Fixed bug in integral not adding a function.

Fixed bug in F3 being invalid turned F1 red.

Made update button wider in functions.

Some internal improvements to make things run more efficiently and reduce file size.

Calculus Tools 0.8.4

Double Integration!!!! - Be patient with older phones this may take a little bit of time to calculate. It takes anywhere from 1-3 seconds on my Droid @ 1ghz running Froyo so I imagine it could be much longer on other models. It is not as accurate as the single integration because otherwise it might takes minutes. Triple integration would take waaaaaaay too long so I'm probably not going to do it.

I also fixed the bug in the derivative activity with the evaluate showing up not where it was supposed to.

Calculus Tools 0.8.3

Trig identities under formulas.

Thanks to Aly for the suggestion.

Calculus Tools 0.8, 0.8.1, 0.8.2

0.8

Math keyboard bundled in the program. You can activate this under settings >> language and keyboard >> calculus tools. To activate it, long press on a text box and choose input method. It will stay active on your phone until you go back to your regular keyboard. I know this is not as easy as keyboards included in some other math applications, but I really didn't want to devote that much screen space to a keyboard all the time.

Thanks to David and John for the suggestion.

0.8.1

Bug fix for keyboard.

0.8.2

Derivative function can do partial derivatives and higher orders.

Thanks to Andrew for the suggestion
