ToolPythonBeginner Minimization with scipy.optimize.minimize: the shape of a seven-atom cluster phi = np.degrees(np.arctan2(pos[ring[0], 1], pos[ring[0], 0]))
ToolPythonIntermediate solve_ivp from the ground up: the pendulum beyond small angles ax.plot(sol.t, np.degrees(sol.y[0]), "o-", color=INK, ms=4)print(np.degrees(theta_at([0.5, 1.0, 1.5])), "nfev =", sol.nfev)
