Discuss on Variation of Parameters

Prime objective of this article is to Discuss on Variation of Parameters. Here explain Variation of Parameters in proper examples and theory. For the differential equation: a (x)y”+ b (x)y” + c (x)y” = d (x); the strategy of undetermined coefficients works as long as the coefficients a, b, and c are constants and also the right‐hand term d( x) is of the special form. If these restrictions do not apply to a granted non homogeneous linear differential formula, then a more powerful means of determining a particular solution should be applied: the method known as variation of parameters.
