About the gCalcD Graphing Calculator with Derivatives

The gCalcD Online Graphing Calculator is the most sophisticated and yet easy to use Java applet (application+let -- small application run on a web page) for graphing functions, parametric curves, equations (including implicitly defined functions and level curves) and plotting points in the Cartesian (rectangular) and polar coordinate systems, and for solving equations and calculating derivatives.

The intelligently designed gCalcD graphing calculator has many unique, innovative features that no other graphic calculators have provided before.

For instance, it is the only known graphing calculator that can identify holes in the graphs of functions, and also draw asymptotes separately from the graphs with dashed lines and cross out those portions of the domain interval where the function is not defined.

It is also the only known online graphing calculator that can graph any arbitrary equation (and not just functions) even in the polar coordinate system.

This graphic calculator automatically appends a default domain to the function expressions, which can then conveniently be modified if needed.

You can also use the gCalcD Graphing Calculator to calculate (symbolic) derivatives of functions and parametric curves. It is the only graphic and derivative calculator with which you can calculate the first few order derivatives and graph them with just one click.

It also accurately solves equations by finding the roots (zeros) of functions without guesswork.

Moreover, gCalcD is also the only known graphing calculator with which you can animate polar and parametric graphs to see where the graphs start and trace.

The gCalcD Graphing Calculator is also the only known graphing calculator that allows rotation of axes and thus allows graphing in non-orthogonal coordinate systems.

Some other features unique to this graphing calculator include the ability to change the scales by clicking on a point on an axis and to drag the graphs to view the required region.

Furthermore, if you make a syntax error, the gCalcD is the only graphing calculator that is intelligent enough to give you feed back by providing a precise error message highlighting the error.
