07.05.2017 · I need to solve a system of two ODE's using improved Euler's (Heun) method. Can any one help as I am pretty bad at Mathematica. This is what I've come up with so far f[t_, x_, y_] = …

In mathematics and computational science, Heun's method may refer to the improved or modified Euler's method (that is, the explicit trapezoidal rule ), or a similar two-stage Runge–Kutta method. It is named after Karl Heun and is a numerical procedure for solving ordinary differential equations (ODEs) with a given initial value. Both variants can be seen as extensions of the Euler method into two-stage second-order Runge–Kutta methods.

An initial value problem for a system of two differential equations is ... such algorithms are Euler's method, Heun's method and the RK4 method.

In mathematics and computational science, Heun's method may refer to the improved or modified Euler's method (that is, the explicit trapezoidal rule ), or a similar two-stage Runge–Kutta method. It is named after Karl Heun and is a numerical procedure for solving ordinary differential equations (ODEs) with a given initial value.

Since yn+1 appears on both sides of the equation, this is an implicit formula which means that we need to solve a system of non-linear algebraic equations ...

One possible method for solving this equation is Newton's method. We can use the Euler rule to get a fairly good estimate for the solution, which can be used as the initial guess of Newton's method. II. Heun's Formula / Improved Euler Method

It is named after Karl Heun and is a numerical procedure for solving ordinary differential equations (ODEs) with a given initial value.

Summarizing the results, the iteration formulas for Heun's method are: xn+1 = xn + h. yn+1 = yn + (h/2) (f(xn, yn) + f(xn + h, yn + h f(xn, yn))) It's now time to implement these newly minted formulas in Mathematica . If you're lost, impatient, want an overview of this laboratory assignment, or maybe even all three, you can click on the compass ...

This is an implicit method: the value y n+1 appears on both sides of the equation, and to actually calculate it, we have to solve an equation which will usually be nonlinear. One possible method for solving this equation is Newton's method. We can use the Euler rule to get a fairly good estimate for the solution, which can be used as the initial guess of Newton's method.
