For the differential equation below, find the first four nonzero terms in each of two linearly independent power series solutions about the origin. What do you expect the radius of convergence to be? NOTE: For y1, set ao = 1 and a1 = 0 in the power series to find the first four non-zero terms. For ya, set ao = 0 and an = 1 in the power series to find the first four non-zero terms. Enter exact answers. (cos x) y" + xy' - 2y = 0. y1(x) = + ... y2(x) + . . Pmin NOTE: Enter co if the series solutions converge everywhere
