This page discusses plotting formulae on Algebra.com. Go to the formula plotting portal for formula, math cartoon and diagram plotting help. You can also see many use examples and live practice with plotting formulas, graphs and cartoons. It is a very powerful system for helping to explain math to children.


Plotting graphs is very easy with my system. The command for it is called graph. It is invoked as follows: 

 graph( xwidth, yheight, xmin, xmax, ymin, ymax, func, func2, ... )

xwidth and yheight are width and height of the graph in PIXELS. xmin and xmax, as well as ymin and ymax, define minimum and maximum x and y values for the system of coordinates used on this graph.


func1, func2 etc are expressions that must be functions of x. You can plot a graph of one or more functions. 

NO VARIABLES BESIDES 'x' are allowed in the function expressions!

Example: 

 graph( 300, 200, 
        -10, 10, 
        -1, 10,
        x^2-1/2, 
        6-x )

would plot a 300x200 pixel graph, with x coordinate between -10 and 10, and y coordinate between -1 and 10, of two functionsL x^1-1/2 and 6-x.
