Approximate analytical and numerical solutions to the damped pendulum oscillator: Newton–Raphson and moving boundary methods

In this work, some new approximate solutions to the damped pendulum equation are obtained. In addition, the Newton–Raphson method (NRM), moving boundary method, and fourth-order Runge Kutta forth-order (RK4) are introduced to analyze the problem under study numerically. With respect to the approxima...
