The Improved Euler’s Method Calculator facilitates the estimation of a dependent variable’s future values based on initial conditions and derivative information at specific time intervals. Its primary function is to compute the predicted and corrected values of a dependent variable at subsequent time steps. The formula for this method involves two crucial steps:

Formula of Improved Euler’s Method Calculator

  1. Predicted_Y1 = Yn + h * f(tn, Yn)
    • Predicts the value of the dependent variable at the next time step.
  2. Corrected_Y1 = Yn + (h / 2) * [f(tn, Yn) + f(tn + h, Predicted_Y1)]
    • Corrects the predicted value using derivative information at the predicted time step.

Here’s a breakdown of the variables involved:

  • Yn: Current value of the dependent variable.
  • tn: Current time.
  • h: Step size (time interval).
  • f(tn, Yn): Derivative of the dependent variable at time tn.
  • Predicted_Y1: Predicted value of the dependent variable at time tn + h.
  • Corrected_Y1: Corrected value of the dependent variable at time tn + h.
