The first two steps of the fourth-order Runge-Kutta method use __________

The first two steps of the fourth-order Runge-Kutta method use __________ Correct Answer Euler methods

All the steps of the Runge-Kutta method use the two-level formulae for initial value problems. The first step uses the forward Euler method and the second step uses the backward Euler method. Collectively, we can say that these two steps use Euler methods.
