Good day! Please help with the answer to one question. I am sure there are people who know ... I hope that the question will not be deleted, since it is not about programming.
In general, the essence of the question: we all know that modifications of the Euler method, namely the Euler broken method and the Euler – Cauchy method for a differential equation, find the desired function only approximately. The question is: is it possible to find the exact solution for any function using both of these methods? If so, for which function can this be done? Thanks in advance for the answer!
