LINEAR DIFFERENTIAL EQUATIONS WITH CONSTANT
Here we describe and illustrate an alternative to the method of undetermined coeffi-
cients for obtaining a particular solution of a linear differential equation with constant
coefficients. The method requires only polynomial differentiation and some elementary
algebra. The procedure has also been expressed as a recursive algorithm. Examples
have been included to show the usefulness of the recursive analogue. Both the technique
and its recursive equivalent can be suitably reformulated for similar difference
equations.
