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 (function graphing calculator), graphing parametric curves (parametric graphing calculator), graphing equations (equation graphing calculator) (including implicitly defined functions and level curves) and for plotting points (point set plotter) using the Cartesian (rectangular) and polar coordinate systems (Polar Graphing Calculator). You can also use the this graphing calculator for solving equations (equation solving calculator) and calculating derivatives (derivative graphing calculator).

The intelligently designed gCalcD Graphing Calculator has many unique, innovative features that no other graphing 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 (Equation Graphing Calculator, Implicit function Grapher, Level Curve Grapher) even using the polar coordinate system . Polar Graphing Calculator

This Online 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 Online Graphing Calculator to calculate (symbolic) derivatives of functions and parametric curves. It is the only Graphing Calculator with which you can calculate the first few order derivatives and graph them with just one click.

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

Moreover, gCalcD 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.

The gCalcD Online Graphing Calculator is also the only known non-orthogonal coordinate systems Graphing Calculator that allows rotation of axes.

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 Online Graphing Calculator that is intelligent enough to give you feed back by providing a precise error message highlighting the error.
