# Diferential equations

2014-07-25

Inspired by this post on /r/maths I made a Runga-Kutta 4-5 integrator. It is interactive, click and drag in the black square below.

## Examples

$\begin{aligned} x' &= \cos y \\ y' &= \sin x \end{aligned}$

$\begin{aligned} x' &= 1.5 y \\ y' &= -y - \sin (1.5 x) + 0.7 \end{aligned}$
