When would one use method of undetermined coefficients and v

Solution

Answer:

(i).Method of undetermined cofficient is the short cut method of General method solving of

Linear differential Equations with constant coefficients.

So if particularly mentioned in the quetion then we shuold follow this method.

(ii) Variation of parameters method is used to solve only second order linear differential

equations with variable coefficients or constant coefficients.

This is also one of the short cut method [or formula] to solve second order linear differential

equations with variable coefficients (or) constant coefficients.

So if particularly mentioned in the quetion then we shuold follow this method.
