Document Summary

Differentiate yp y =p u y +1 1 y =p y u +1. 1 y =p u y +1 1 y u +1 1 u y +1 1 y u +1 1 u y +1. 1 u y2 2 u y +2 2 u y +2 2 y u2 2 y u +2. Substituting the derivatives in this equation y +p. With two desired equations, we can find the solution of the system by. Cramer"s rule y u +1 1 y u +1 1 y u =2 2 y u =2 2. 3. 5 variation of parameters1method of variation of parametersintegral-defined functionshigher-order equations y " . 4m + 4 = (m " 2) =2.
