WebThe first argument is the function f, the second one determines the time interval on which to solve the IVP in the form [initial time, final time], and the last one specifies the initial value of y. The output of ode45 consists of two arrays: an array t of discrete times at which the solution has been approximated, and an array y with the ... 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!

WebThis differential equation is separable, so we can solve it: d d x μ = 3 μ d μ μ = 3 d x ∫ d μ μ = ∫ 3 d x ln μ = 3 x + C μ = A e 3 x, A > 0 μ = A e 3 x, A ≠. . (You'll need to solve an auxiliary differential equation ( x) = q ( x) ( x) ). Then solve for y, and use the initial value. Webwhere y1 ( t) and g ( t) are solutions of the following IVPs: a¨y1 + b˙y1 + cy1(t) = 0, y1(0) = 1, ˙y1(0) = 0, and a¨g + b˙g + cg(t) = 0, g(0) = 0, ˙g(0) = 1.
