The 4th order Runge-Kutta method is a numerical integration technique used to solve ordinary differential equations. It was developed by Carl Runge and Martin Kutta in 1901. The method is based on the idea of breaking the problem down into small steps and using these steps to approximate the solution.

To use the 4th order Runge-Kutta method, we first need to determine the initial value of the function we want to solve. We then use this initial value to calculate the values of the function at each step. The method is iterative, meaning we use the previous solution to compute the next one.

The steps involved in the 4th order Runge-Kutta method are as follows:

1. Calculate the value of the function at the beginning of the interval.

2. Calculate the value of the function at the midpoint of the interval.

3. Use the midpoint value to calculate the slope of the function.

4. Use the slope to estimate the value of the function at the end of the interval.

By repeating these steps, we can approximate the solution to the differential equation. The 4th order Runge-Kutta method is widely used because of its simplicity and accuracy.
