Summary description: Draw graphs of functions in 2D, using TikZ and LuaLaTeX
Announcement text: -------------------------------------------------------------------------------- tkz-fn draws graphs of functions with TikZ; all computations are done by Lua, so the package requires LuaLaTeX. It is the successor of tkz-fct: gnuplot, fp.sty, tkz-base and --shell-escape are no longer needed. All macros begin with \tkzFn, so tkz-fn and tkz-fct can be loaded together.
Features: - curves y = f(x), parametric and polar curves, interrupted at vertical asymptotes and where the function is not defined; - tangent lines (with one-sided tangents), areas under or between curves, Riemann sums (left, right, mid, inf, sup); - points on curves, coordinates, labels, vertical and horizontal lines, data plots; - values, derivatives, integrals and Riemann sums computed by Lua and printed in the text; - numbers in American (3.14, (a, b)) or French (3,14, ]a ; b[) format; - axes as in school textbooks, with arrows at one or both ends, or "box" axes as with pgfplots, selected by an option; - optional bridge to tkz-elements: points defined by tkz-fn are exported to the table z.
The documentation is available in American English (tkz-fn-en.pdf) and in French (tkz-fn.pdf). --------------------------------------------------------------------------------
