Math 322Assignment 16, Spring 2013Due at 3 PM Friday May 10th1. For each of the following systems, draw a phase portrait illustrating the behavior of the solutions,using the phaseplane plotter that can be found at the class web page. Be sure to•include any trajectories along eigenvectors, which you may just have to put in “by hand”•include enough trajectories to give a good idea what is going on in all parts of the phase plane•put an arrowhead or two on each trajectory to indicate direction as tie increasesIn each case, try to predict what the phase portrait will look like before ±nding it.(a)x′=b−2−2−12−2Bxλ=−3,−1,k=b21B,b−21Bx=c1b21Be−3t+c2b−21Be−t(b)x′=b22122Bxλ= 3,1,k=b21B,b−21Bx=c1b21Be3t+c2b−21Bet(c)x′=b1232Bxλ= 4,−1,k=b23B,b−11Bx=c1b23Be4t+c2b−11Be−t(d)x′=b3003Bxλ= 3,k=b21B,b−21Bx=c1b21Be3t+c2b−21Be3t(e)x′=b2−114Bxλ= 3,k=b−11Bx=c1b−11Be3t+c2±b−11Bte3t+b
