(1) For the following systems of ODEs, find the general solutions (in vector form), ygen. Make sure that your solutions only contain purely real vectors, i.e., the imaginary unit, '2', should not appear in your solutions. y1 = 2y2 y = -2y1 (b) { y = 8y1 - 9y2 y = 4y1 - 4y2 (a) { General Solution for (a): General Solution for (b):

(ii) The procedure of finding series solutions to a homogeneous
linear second-order ODEs could be accurately described as the
“method of undetermined series coefficients”.
(iii) The underlying idea behind the method of undetermined
coefficients is a conjecture about the form of a particular
solution that is motivated by the right-hand side of the equation.
The method of undetermined coefficients is limited to second-order
linear ODEs with constant coefficients and the right-hand side of
the ODE cannot be an...
A.9. First-order linear non-homogeneous ODEs having one dependent variable are of the form dy + P(x)y = f(x). Beginning with yp = uyż, where yı = e-SP(x)dx and is thus a solution to Y + P(x)y = 0, and given that the general solution y = cyı + Yp, use variation of parameters to derive the formula for the general solution to first-order linear non-homogeneous ODES: dx y = e-SP(x)dx (S eS P(x)dx f(x)dx + c). You may use the...
