&kmplot; is a mathematical function plotter for the &kde; Desktop. It has a powerful built-in parser. You can plot different functions simultaneously and combine them to build new functions. Examples Examples &kmplot; supports parametric functions and functions in polar coordinates. Several grid modes are supported. Plots may be printed with high precision in the correct scale. &kmplot; also provides some numerical an 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.
