1.	The first two steps of the fourth-order Runge-Kutta method finds the value at which point?(a) At the (n+0.5)^th point(b) At the (n+1)^th point(c) At the (n-1)^th point(d) At the n^th pointI have been asked this question at a job interview.This intriguing question comes from Transient Flows in portion Transient Flows of Computational Fluid Dynamics
Answer» The CORRECT choice is (a) At the (n+0.5)^TH point Explanation: The first two STEPS of the fourth-order Runge-Kutta method find the values at the (n+0.5)^th point. It does not DIRECTLY move to the next step. It finds the value at an intermediate point between the current and the next POINTS.
