Label each of the following statements as true or false. If true, prove the statement. If false, provide a counterexample. (a) If the characteristic equation of a constant-coefficient, linear, homogeneous ODE has one non-real root, then it has at least two non-real roots. (b) Let a, b, c, xo, x1, Yo, Y1 E R and xo # yo, a # 0. Then the ODE ay" + by' + cy satisfying y(xo) = yo and y'(x1) = y1 is guaranteed a unique solution. be polynomials of degree n with domain R. If there exists c E R such that (c) Let W [p, q](c) = 0, then (d) Suppose the general solution of a linear, second-order ODE is y = C1yı + C2Y2 with domain D, where C1, C2 E R. Then for any x € D, W[y1, y2](x) 7 0. and and q are linearly dependent. %3D sin(t)
