WebJan 12, 2024 · @John: You also need to alter your solve_ivp call to something like: solve_ivp (function2, (0, 100), (v0, 0), t_eval = t). This sets the initial condition to y (0) = v0, and y' (0)=0. The original code uses (0,0) for the 3rd argument, which implies v0 = 0, which reduces v0*cos (kt) to a flat line. – unutbu Jan 13, 2024 at 3:02 @unutbu Thanks!
