y2 (2) f (z ) y1 (z) f (z) Up = -yl(x) W(x) da + yz(x) dx W(x) C. Compare your answers from part A. and B. to confirm that they de- scribe the same function (but maybe in different ways).3. Find two linearly independent solutions and their wronskian of the following second order differential equation y" - 8y' + 15y = 0. A. Then find the particular solution of the nonhomogeneous equation y" - 8y' + 15y = test using the method of undetermined coefficients assuming that the particular solution is of the form yp = atest + bt2e3t. B. Then find the particular solution of the nonhomogeneous equation y" - 8y' + 15y = test using the formula
