Chapter 5.3, Problem 24E

To determine

To find:

The motion of the pendulum when,

$\begin{array}{rll}{\theta }_0& =& 0.05\\ {\theta }_1& =& 0\\ l_0& =& 1\\ l_1& =& 0.1\end{array}$

$\omega =1$,

and $\varphi =0.02$.

and check whether the pendulum attains an angle $\theta$ greater in absolute value than the initial angle ${\theta }_0$.
