- 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: [2]. The 3/8 factor multiplies k_3, not k_2. I was unable to edit the equation in the article myself. Adamace123 (talk) 20:44, 22 July 2014 (CEST)
