Method of undetermined coefficients. Connected to: From Wikipedia, the free encyclopedia.The determination of an unknown function in the form of an exact or approximate linear combination (finite or infinite) of known functions. This linear combination is taken with unknown coefficients, which are determined in one way or another from the conditions of the problem in question.The above theorem shows that we can always reduce the problem of finding a particular solution to a nonhomogeneous equation to the case when the input function does not contain an exponential multiple. We illustrate the method of undetermined coefficients in the series of examples. In this section, we will discuss using the method of undetermined coefficients to find a particular solution, Y, to a 2nd order, constant coefficient d.e. L[y]=g(t). Outline of method of undetermined coeffients: 1. Requires an initial assumption on the general form of Y(t), with unspecified coefficients 2. Jun 16, 2009 · For example, consider this problem: * Find the solution to the differential equation y' = t^4. To do so, we first find the solution to the corresponding homogeneous differential equation y' = 0 ; this is simply y = C (because the functions which have derivative 0 are just the constant functions). The method of undetermined coefficients notes that when you find a candidate solution, y, and plug it into the left-hand side of the equation, you end up with g(x). Because g ( x ) is only a function of x , you can often guess the form of y p ( x ), up to arbitrary coefficients, and then solve for those coefficients by plugging y p ( x ) into ...
