Runge Kutta Method MCQ

1. Consider the first order initial value problem

y’ = y + 2x – x2, y(0) = 1, (0 ≤ x < ∞) with exact solution y(x) = x2 + ex. For x = 0.1, the percentage diference between the exact solution and the solution obtained using a single iteration of the second-order Runge Kutta method with step size h = 0.1 is

  1. 0.06%
  2. 0.07%
