Use the Laplace Transfam Method to solve the following I.V.P's. Give the explicit solution, its Laplace trausfum and produce a plot of the solution as phase plane plot for each problem. i) y"+6 Y'+87= h (4) well as a Y'(o)=2 YC0-0) O h(t) = { osta 5 52t clo t210 ii) y'+ y = f(t-2) 5 (7-8) Y(ol = 0, y'o) = - o Oltul ) iii) y"+y = f(t) ) Yco) - o, Y). fit). square wave fo otherwise 5 denotes the Delta function discussed in Section 5.6.
