About the gCalcD Graphing Calculator

Free online graphing calculator for graphing functions in the Cartesian and Polar coordinate systems. Free online graphing calculator for graphing equations in the Cartesian and Polar coordinate systems. Free online graphing calculator for graphing parametric equations of 2D curves in the Cartesian and Polar coordinate systems. Free online graphing calculator for graphing point sets (table of values) in the Cartesian and Polar coordinate systems. Online calculator for finding zeros (roots) of functions. Online calculator for calculating derivatives of functions and parametric equations (curves).Online graphing calculator for graphing in perpendicular and non-perpendicular coordinate systems.

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 gCalcD graphing calculator is the web's most powerful and intelligently designed 2D graphing and derivative calculator that has many unique, useful, innovative features that no other graphing calculators and derivative 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 by 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 polar coordinate system.

This graphing 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 even parametric curves. It is the only graphing 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.

It is also the only known online graphing calculator which allows graphing in both Cartesian (rectangular) and polar coordinate systems. Particularly, it is the only known graphing calculator that allows graphing equations and parametric curves in polar coordinate system. Moreover, it is also the only known online graphing calculator with which you can animate polar and parametric graphs to see where the graphs start and trace.

It 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 and derivative 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 and derivative calculator that is intelligent enough to give you feed back by providing a precise error message highlighting the error.

The gCalcD Graphing Calculator is indeed the most advanced online graphing calculator, full of powerful innovative features, and yet exceptionally convenient to use.
