KmPlot is a mathematical function plotter by KDE. It has a powerful built-in parser. You can plot different functions simultaneously and combine them to build new functions.

KmPlot supports several different types of plots:

Explicit cartesian plots of the form y = f(x).

Parametric plots, where the x and y components are specified as functions of an independent variable.

Polar plots of the form r = r(θ).

Implicit plots, where the x and y coordinates are related by an expression.

Explicit differential plots.

KmPlot also provides some numerical and visual features like:

Filling and calculating the area between the plot and the first axis

Finding maximum and minimum values

Changing function parameters dynamically

Plotting derivatives and integral functions.

These features help in learning the relationship between mathematical functions and their graphical representation in a coordinate system.
