... is a simple tool to plot curves of functions
(rsp. their derivatives or integrals) in cartesian coordinates. Use it to to display
common mathematical functions or expressions as jpeg, png or gif image.

The lower tab allows to calculate tables of function values (in csv, text or laTeX
format) and get a hyperlink to reproduce an image on the fly (using an URL or QRcode).

Enter an expression and some variable values below, then hit calculate
to produce sample points

Enter some variable values and a formula to be calculated,
functions defined for the plot above can be copied using one of
the buttons labeled f(x), g(x) or h(x). Variables will usually be
simple numbers, separate multiple input values (x) by spaces.

Select one of the checkboxes to chose a format for your samples:

results - a string of function values, separated by spaces

table - a simple html table including variable values

csv - colon separated values including variable values

latex - code to layout a table including variable values in laTeX
