# what is the formula for runge kutta three dimension [closed]

i have ODE as d^2y/dt^2 = x^2 + y^2 + z^2

what is the algorithm of runge kutta for this equation. initial conditions are x = 100, y = 0 , z = 0 and h = 1

• This question is very unclear. For instance, what are $x$ and $z$? Are they also functions of $t$? Do we know them, or are they also unknowns? You say $x = 100, y = 0, z = 0$, but that makes it sound like $x, y, z$ are numbers, not functions. Finally, what have you tried yourself? You must at least know the general statement of the Runge-Kutta method (of which order, by the way?) What stops you from applying it in this case? – Arthur Feb 1 '18 at 8:18
