ToolPythonBeginner Numerical integration with scipy.integrate: the area under a measured peak theta0 = np.radians(90)
ToolPythonIntermediate solve_ivp from the ground up: the pendulum beyond small angles theta0 = np.radians(90)th0 = np.radians(theta0_deg)T_exact = 4 * np.sqrt(L / g) * ellipk(np.sin(np.radians(a_fine) / 2) ** 2)
