A mathematical model for the position x(t) of a moving

Chapter 4, Problem 24E

(choose chapter or problem)

A mathematical model for the position x(t) of a moving object is

\(\frac{d^{2} x}{d t^{2}}+\sin x=0\)

Use a numerical solver to graphically investigate the solutions of the equation subject to \(x(0)=0, x^{\prime}(0)=x_{1}\) \(x_{1} \geq 0\). Discuss the motion of the object for \(t \geq 0\) and for various choices of x1. Investigate the equation

\(\frac{d^{2} x}{d t^{2}}+\frac{d x}{d t}+\sin x=0\)

in the same manner. Give a possible physical interpretation of the dxdt term.

Text Transcription:

d^2xdt^2+sinx=0

x(0)=0,x^prime(0)=x_1

tgeq 0

d^2xdt^2+dxdt+sinx=0
