【實用教育app】TKalculator Free|最夯免費app

TKalculator Free is a scientific calculator supporting calculations with real and complex numbers, with capabilities to plot 2D and 3D functions and statistical analysis of linear regression models.

Main features:

-Complete scientific calculator yet simple and easy to use;

-Polynomial equation solver;

-Drag/slide for scrolling the graph and pinch to zoom in real time;

-Full support for Real and Complex math calculations with a large range of functions for Complex numbers;

-Support for “real & imaginary” or “magnitude & angle” complex formats;

-Supports graphing of parametric and polar equations;

-Find equations roots, trace points, maxima and minima;

-Support for 3D surface graphs;

-See how the shape of an equation in the rectangular coordinate system looks like in the polar form and vice-versa;

-Support for plotting Cartesian equations along the vertical axis (X=f(Y)) and trace constants equations (horizontal and vertical lines);

-Statistical support for simple linear regression (with 2 variables) with validation of the regression model by the T-Test method and Analysis Of Variance (ANOVA).

-Support for user variables (eg T:=5, calculate T+T/2).

-User manual available.

Release 1.3.0.0 - What's new?

- *NEW* Support for user variables (eg T:=5, calculate T+T/2).

- Fixed problems with the plotting of certain equations of 2D and 3D graphics.

- Better handling of data errors for 3D graphics (eg division by zero and infinite values are now ignored and are not plotted).

- Correction of faults at the level of the 3D graphics user interface.

- General improvements in the application's user interface.
