The most common Runge-Kutta order…

y_{i + 1} \approx y_{i} + \frac{Δ t}{6} (k_{1} + 2 k_{2} + 2 k_{3} + k_{4}) : ⎩ ⎨ ⎧ k_{1} = g (t_{i}, y_{i}) k_{2} = g (t_{i} + \frac{Δ t}{2}, y_{i} + \frac{Δ t}{2} k_{1}) k_{3} = g (t_{i} + \frac{Δ t}{2}, y_{i} + \frac{Δ t}{2} k_{2}) k_{4} = g (t_{i} + Δ t, y_{i} + Δ t k_{3})
