WebThe damped driven pendulum is modeled using : d2 (x)/d (t2) + b*d (x)/d (t) + sin (x) = F*cos (x). (4) Numerically simulate (4) with b=0.22 and F=2.7. a) Starting from any reasonable initial condition, perform a phase portrait analysis. Show that the time series has an erratic appearance, and interpret it in terms of the pendulum's motion. b ... WebDec 31, 2024 · While the new integrators or solve_ivp, respectively, can compete with ode for large differential equations, it is up to twenty times slower for small ones, which suggests a massive overhead. This is not so nice, in particular considering that ode already has a considerable overhead when compared to odeint (which mostly comes through the latter …
