I am trying to examine the accuracy and stability of the Eulerand the predictor-corrector method applied to a pendulum. Howevermy final result is wried, the result of a pendulum should be like awav Euler method \[ \left\{\begin{array}{c} x_{k}=x_{k-1}+v_{k-1} \Delta t \\ v_{k}=v_{k-1}-\left(\omega_{0}^{2} x_{k-1}+\gamma v_{k-1}\right) \Delta t \end{array}\right. \]import matplotlib.pyplot as p 1 answer
