Plotting Formulas

This page discusses our math formula plotting system. has a nice feature where tutors who create their solvers, lessons and answer user questions, can enter simple text and have it drawn as nice mathematical formulas. Unlike the LaTEX based system that is used in Wikipedia, for example in this quadratic equation page, my system is easy to use for any student or school teacher.

That said, I also have a TeX support also, for TeX fans.

My formula plotter does a lot more than you might expect. See the guide.

Formulas are entered using symbols {{{ and }}} (curly braces). They tell my server that the text you are entering is not simple text, but instead should be drawn as a formula. Example of a formula: {{{ x = sqrt( (y-z)/(y z) ) = 2 }}}. I have a special page where you can practice entering formulas.

         graph( xsize, ysize, xmin, xmax, ymin, ymax, func1, func2... )

xsize and ysize are dimensions of the graph in pixels. xmin, xmax, ymin and ymax define the area of the coordinate plane that is being drawn. The list of functions that follow, are expressions involving only one parameter, x.

 graph( 300, 200, 
        -5, 5, -5, 5,

So, format your expressions as you like.
