sin θ/ 2 − 1 = 0 solve. Find all solutions of the equation & the solutions in the interval [0, 2π).

<p>Assume thatx(t)=b9cos(&#969;_ot)+u(t) is a solutionof the vander Pol Equation 4.19. Assume that the dampingparameter&#160;&#956; is small and keep terms in u(t) tofirst order in &#956;. Show that b= -2a and u(t)=-(&#956;a³/4&#969;_o)sin(3&#969;_ot)is a solution. Produce a phase diagram of x' vs x and produce plotsof x(t) and x'(t) for values of a=1,&#969;_o=1, and&#956;=0.05.</p>
