# Graphing Calculator | Polar | Function, Equation, Parametric | Intercepts

The world's most advanced Online Graphing Calculator, deploying the most sophisticated Cartesian and Polar coordinate systems, with which you can construct polar and parametric graphs by animation to see how they are traced; alsograph with axes rotated too!

Advanced Online Graphing Calculator for graphing function, equation (with variables on both sides) and parametric curve. This intelligent graphing calculator automatically detects the type of expressions and graphs as you type using this syntax in the Cartesian or polar coordinate systems. This sophisticated graphing calculator is the world's first and the only known graphing tool that lets you animate polar and parametric graphs to visualize how they are traced and constructed from start to end. Other easy-to-use features of this graphing calculator allow you to find all the x-intercepts (zeros or roots of functions) on a bounded interval with a single click and label axes with π or any number. This function and parametric derivative calculator finds and also graphs derivatives. Full instruction

• This Graphing Calculator, with many unique features, can be used to graph functions, equations and parametric curves using the Cartesian and polar coordinate system.
• Trace polar and parametric graphs by pressing the Animate button. This Polar Graphing Calculator and Parametric Graphing Calculator are the only graphing tools that show you how these types of graphs are constructed from start to end.
• Calculate the x-intercepts (zeros or roots) of a function.
• Graph derivatives of functions and parametric equations.
• This unique Graphing Calculator is the only graphing tool that lets you rotate axes to graph in non-perpendicular coordinate systems.
