Chapter 6, Problem 3P

The tip of a one-link robot is located at $\theta =-\pi /4\text{rad}$ at time $t=0$ s as shown in Fig. P6.3.The robot is rotating at an angular frequency of $2\pi \text{rad/s}$ .If $l=20$ cm, plot the $x-$ and $y-$ components as a function of time. Also find the amplitude, frequency, period, phase angle, and time shift.
