3 Runge-Kutta Methods - IIT
math.iit.edupredictor for the (implicit) trapezoidal rule. We obtain general explicit second-order Runge-Kutta methods by assuming y(t+h) = y(t)+h h b 1k˜ 1 +b 2k˜ 2 i +O(h3) (45) with k˜ 1 = f(t,y) k˜ 2 = f(t+c 2h,y +ha 21k˜ 1). Clearly, this is a generalization of the classical Runge-Kutta method since the choice b 1 = b 2 = 1 2 and c 2 = a 21 = 1 ...
