» Smart Algebra Description
Smart Algebra 3.01 builds graphs of any complexity (including implicit functions) in the polar and Cartesian coordinate systems, quickly draws the image on the screen, allows the analysis function (search for extrema, integral in the interval, minimums and maximums), to determine the value of a function at a point to keep the schedule in bmp-format. The program provides several modes of increase for the most comfortable work.

Features::

* The program is written in C++ so it has maximum performance and quick start.
* Support for English, Russian, Czech languages
* Full screen
* Works on all resolutions correctly (starting from 240*176 to 800*480)
* Construction time up to nine plots (each graph, you can choose the color).
* Trace - tracking feature lets you move the pointer on the schedule and read the values of the function.
* Box - Draw a box around the desired area, then this area will be increased (Move the viewing area, trace the area to increase the possible finger/stylus /joystick)
* Automatic rescaling
* Out / In the change of scale in accordance with the coefficients given in the Factor.
* QUICK - a rapid change of scale (a few defined scope).
* Calculator - a simple calculator.
* Picture - lifting screenshot of the screen (to save images in the folder My Documents).
* Support for graphing in polar coordinates.
* Plotting given in parametric form. (To do this in the box you must enter the two functions separated by semicolons).
* Supported functions: sin, cos, tg, log, ln, lg, sh, ch, th, exp, acos, asin, atg, int, frac, abs.
* Numerical analysis of functions on the interval (Finding roots, maximum, minimum)
* AutoComplete function names (only for PocketPC)
* Select from the list of functions (only for smartphones, is activated by pressing the "Green tube)
* Support special. functions: Gamma, Si, Ci, Shi, Chi, Psi, DawsonF, Ei, Sf, Cf, Ai, Bi, erf, Li, I, J, K, Y, Hyper, Cheb, Hi, Lag, Leg
* Built-in Help
* Construction of implicitly defined functions
* Approximation and interpolation of data from file

Last changes (version 2.9):
* Fix registry error
* Increased speed
* Fixed memory leaks, improved working memory
* Errors lookup in Trace mode

Last changes (version 3.0):
* Fixed some bugs
* Construction of implicitly defined functions
* Approximation and interpolation of data from file
* Added display of values of the derivative on the main screen
* Save the file analysis function
* search integral and mean value in the interval

Last changes (version 3.01):
* Support for Czech language (by Nallim)

I don't NEED this app. But it seems to work great. I'd use it if I was back in school.
