Would love it if someone helped out thanks! 4. Find the general solution to each of the following non- homogeneous second order ODES. day dy a) dx2 dx + y = -x + 3 Hint: Use the method of undetermined coefficients in finding the particular solution. - 2
2 d²v Consider the non-homogeneous linear equation X 2 dy + 3x4 dx +y=e* dx? A particular solution to this equation can be obtained only by the method of undetermined coefficients. only by the method of variation of parameters. No method available. by both, he method of undetermined coefficients, and method of variation of parameters.

IGNORE (i) (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...
