NUMERICAL Euler's Modified Euler's Midpoint runge kutta Multistep Predictor Corrector System of First Order Ordinary Differential Solving a Higher Order Initial Value Use of MATLAB Built In Functions for Solving Initial Value Local Truncation Error in Second Order Range kutta Step Size for Desired Stiff Ordinary Differential Background Ordinary differential equation A differential equation that has one independent variable A first order ODE The first derivative of the dependent variable with respect to the independent variable Example Rates of water inflow and outflow The time rate of change of the mass in the tank Equation for the rate of height Background Time dependent problem Independent variable: time Dependent variable.
10.5 Runge‐Kutta Methods Second‐order Runge‐Kutta Methods General form The values of these constants vary with the specific second‐order method. Modified Euler method and the midpoint method – Two versions of a second‐order RK method Modified Euler method: ? 5 L 5 6, 6 L 5 6, 61, > 6 51
