of Mathematics, Rajshahi University of Engineering and Technology (RUET), Kazla, Rajshahi-6204, Bangladesh The classical harmonic oscillator can be associated to the differential equation: The differential equation that governs the motion of a pendulum is given as In solving the Schrödinger equation, we will start with one of the simplest interesting quantum mechanical systems, the quantum mechanical harmonic oscillator. 2 Let’s first define our quantum harmonic oscillator. The general form of the Schrödinger equation for a one-dimensional harmonic oscillator reads thus: \begin{equation} \label{eq:sch} 2020-12-01 · This paper focused on solving the nonlinear equation of circular sector oscillator by the global residue harmonic balance method. The approximated solutions with high accuracy were obtained and compared with some existing methods. Numerical results shown the efficiency of GRHBM over MHPM and AG. 2020-11-23 · 2.

This means if we know the initial conditions x ( t = 0) and x ˙ ( t = 0) we know the energy, and we can use that to find the position and velocity at later times. In particular, as x ˙ 2 decreases x 2 must increase, and x ˙ 2 can't be smaller than 0 so | x | is maximum when. 1 2 k x 2 = E. or. x m a x = 2 E k.

We will solve this K m k cos and sin equation. this solve that will functions least two at know We. )( )( However, we can always rewrite a second order Let's again consider the differential equation for the (damped) harmonic oscil- the spring, our solution should take the form of an oscillation function with a.
