“…Many numerical methods have been applied for solving linear and non-linear differential equations [13][14][15][16]. One of the most popular physical models encountered in undergraduate courses is the simple pendulum and the differential equation describing its motion [14,15,[17][18][19][20][21][22][23][24][25]. Historically, the equation arises when studying the oscillations of a pendulum clock, but also appears in various other areas of physics, since problems often can be reduced to a differential equation similar to that describing the pendulum [16,21,22,26,27].…”
