Slope Field Grapher

How does this work?

This is an interface where you can enter standard Javascript code with the following additional functions and constants: e, pi, exp(), cos(), sin(), tan(), sqrt(), abs(), ln(), arctan(). It automatically plots a slope field for the differential equation dydx=F(x,y).\frac{dy}{dx} = F(x,y).

There is also a custom plot() function that will graph any function you add. The default viewing window has -5 ≤ x ≤ 5 and -5 ≤ y ≤ 5.
