This app plots a curve based on the parametricfunctions x=f(t) and y=g(t), which are entered by the user in thefirst window. The user can also enter the range of the variable tas signed integers (ie. they can be negative). I've provided anexample curve. The functions are:f(t)=200 cos(t) sin(sqrt(2)t)g(t)=200 sin(t) sin(sqrt(2)t)This plots a rose petal curve.There are lists of operators, functions and constants that canbe used. 't' is the only variable.When the draw window opens, you'll get a toast that tells youhow long time it took to calculate and draw the points. Be carefulnot to enter too high values for t.

When you create an image, you specify thesizeof a grid, which is placed on top of the image. When you clickon asquare in the grid, it's filled with color. Click again toremovethe color, leaving the square transparent. The image is savedin asimple xml-format, but it can also be exported asaPNG-image.
