For example: for an exponential, aekt, guess y p = Aekt; for a polynomial (or monomial) of degree n, guess y p = C 0 +C 1t +:::+C ntn (a polynomial of the same degree). Multiply yp by t until it contains no part of the complementary solution. Plug yp into the DE and solve for the constant(s). Doreen De Leon Euler-Cauchy Using Undetermined ...

Mar 23, 2010 · You always need to find the general solution first as this affects the particular solution. In this case it is y = a*e^-x + b*x*e^-x. Particular solutions to differential equations of this sort are usually very similar to the right hand side but in this case you already have b*x*e^-x as part of the general solution.

Differential Equations and Linear Algebra, 2.6b: An Example of Method of Undetermined Coefficients - Video - MATLAB & Simulink Consider y 000 - 3 y 0 - 2 y = 3 e - x . Solution We saw in a previous example that the general solution of the corresponding homogeneous is: y h ( x ) = c 1 e - x + c 2 xe - x + c 3 e 2 x . Since both e - x and xe - x are solutions of the corresponding homogeneous, we will look for a particular solution.
