Controls:

With consecutive pushing of this button you can choose: "1", delimiter of the number ",", "square root - sqrt", "n-th root - nthroot", "integral - int", "function to find roots of equations - solve". To lock any variant just stop pushing this button 1 second.
-
With consecutive pushing of this button you can choose: "number related to the button", "symbols related to this button". To lock any variant just stop pushing this button 1 second.

With consecutive pushing of this button you can choose: "plus operator", "minus operator", "multiplication operator", "division operator", "exponentiation operator", "plus/minus operator", "factorial", "vector multiplication operator". Also with this pushed button you can highlight the part of equation by using Left/Right buttons.

By "clicking" on this button program will numerically calculate equation (this means "="); by pushing button more than 0,4 sec. program will symbolically calculate equation (this means "->"). Also, if the cursor located on the right of the not defined variable or not defined function this button will create a definition operator (this means ":=" ).

Removing last character (Backspace). In the mathematical reference book this button means "Back".

Bahasa Indonesia [IND] translation file for SMath Studio 0.88 updated: Text_IND.lang. All interface strings updated. Example files from the Examples Dialog updated as well and they will be available in the next version of SMath Studio later.

To install IND language update to the program, please, just put the downloaded Text_IND.lang file to the lang folder of installation directory of SMath Studio (by default it is C:\Program Files\SMath\SMath Studio) and then start the program.

Thanks to Waluyo Adi Siswanto for this great help!

Hello!

A small hint for Gentoo Linux users:

For properly work of SMath Studio you must to (re)compile dev-dotnet/libgdiplus package with cairo flag on - otherwise all pull-down menus will be broken and fonts/symbols on workplace will be overlapping.

Sorry for my bad English - my native language is Polish

Regards.

Many thanks slan for the tip!

By the way, one who want to get updated interface translation or check for new available interface languages for SMath Studio can visit this page: http://smath.info/translator/. This web-service also provides an interface to simply correct existing translations or make some new one(s).

Regards.

I wish to express my gratitude for people like you...
Thank you for this program... Thank you for sharing it too...

Thank you, skyxda!

I've got an update, single file, tutorial for version 0.88 (April 2010), including unit applications and references to the new menu items in SMath Studio.
