Diferential equations

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

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

view here.

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

view here. Suggested by /u/qwertz_guy.
