this is a backdated entry made specially for those who don't speak russian but have interest in cannabola and the history of its creation. You may find the original entry here, also with the whole story...
6 march 2005, supman & biojane created the first cannabola formula:
R = (1+sin(t)) (1+.9cos(8t)) (1+.1cos(24t))
here's the plot in polar coordinates (built in Maple 7) of this function:
UPDATE: k001 conducted an independent expertize that makes it clear that the formula is correct
UPDATE: qnick gave function a name "cannabola", also he made it's graph in MS Excel
UPDATE: stasikoffjj modernized a formula with addition of perturbation coefficient which helped the graph look more like the original leaf, here's his variant of cannabola
UPDATE: shfire suggested the folowing variant:
R = (1+sin(t)) (1-.9abs(sin(4t))) (.9+.05cos(200t)),
and a new cannabola graph, i think it's the best
UPDATE: winwolf made graph using macromedia flash technology, here are plots of cannabola: my version, the version of stasikoffjj , & the version of shfire
UPDATE: djon_jene4ka named cannabola the formula of love to graphs, funny
UPDATE: dammazz & friends made a php script that generates a very beatiful cannabola plot!
UPDATE: an anonymous coder created a cannabola java-applet - it is available here with source
UPDATE: a coder Tosol from Kharkov, Ukraine made a program for drawing a plot with variable detalization: cannabis has got you!
UPDATE: it had to happen so it happened - real mathematician made his contribution on cannabola
sir Anton Sukhinov created a cannabola-like fractal. There is nothing from the original function in it but it looks very much like the prototype, anyway you must see it because of it's exceptional beauty!
