This method takes twice the number of function evaluations than Euler's method, though it gives more accurate results it takes more time of execution. So a change of just $0.002$ in the step-length has completely changed the behaviour of the numerical solution. 2. . Euler's method uses the simple formula, to construct the tangent at the point x and obtain the value of y(x+h), whose slope is, In Euler's method, you can approximate the curve of the solution by the tangent in each interval (that is, by a sequence of short line segments), at steps of h. In general, if you use small step size, the accuracy . And all else fails far more often than not. The basic approach for solving Eulers equation is similar to the approach used to simplify the constant-coefficient equations. Here are a few hand-picked blogs for you! For example, the use of genetically modified crops may lead to the creation of "superweeds" that are resistant to herbicides. This scheme is called modified Eulers Method. This is part of <>stream
This method was given by Leonhard Euler.
