In numerical analysis, the Runge–Kutta methods (English: RUUNG-ə-KUUT-tah) are a family of implicit and explicit iterative methods, which include the Euler method, used in temporal discretization for the approximate solutions of simultaneous nonlinear equations. These methods were developed around 1900 by the German mathematicians Carl Runge and Wilhelm Kutta.
I have two different methods giving different results
Why is this the case? (Left method was answer in solutions, right method was my answer before checking the solutions). Also yes pretend V was V_1 or something ignore my dummy variables :)
