View source for Talk:Kutta-Merson method

The expression for k_4 in Eq. (2) has a mistake. The second argument to f should be y_0 + 1/8 k_1 + 3/8 k_3.
: Thank you. I am not an expert in it. Trying to check it, I look on Wikipedia: [https://en.wikipedia.org/wiki/List_of_Runge%E2%80%93Kutta_methods#3.2F8-rule_fourth-order_method], but I do not understand, is it the same or not?

::The explicit Runge-Kutta method listed on this page does not appear, currently, on that Wikipedia page. I verified my correction by consulting the article's reference 1: [http://link.springer.com/article/10.1007%2FBF02165587]. The 3/8 factor multiplies k_3, not k_2. I was unable to edit the equation in the article myself. [[User:Adamace123|Adamace123]] ([[User talk:Adamace123|talk]]) 20:44, 22 July 2014 (CEST)
