SECTION : Mapping Fields   

NOTE: You must be connected to the Internet the first time you view this simulation, at which point the codebase for all the simulations will be downloaded to your computer. This process make take a few minutes, as the codebase is roughly 9MB in size. Subsequent viewings of the applets will run from your local copy.

This applet allows you to see how various analytic functions look in a "grass seeds" representation, letting you visualize the functions more clearly. You can also explore the set of curves which are perpendicular to your analytic function (these are equipotentials if the your function corresponds to an electrostatic field). Enter the x-component of your analytic function in the top text box of the application, using standard convections (i.e. "*" for multiplicaton, "/" for division, "^" for exponents). Enter the y-component of your analytic function in the bottom text box. Then choose either "grass seeds" or "equipotentials" depending on what you want displayed.

The image displayed to the left has an x-component of tan(y^3) and an y-component of 3*y*tan(x^3) (thanks to Michael McGraw-Herdeg).
