On the 3rd order linear differential equationDOI: 10.3126/kuset.v8i2.7319, PP. 7-10 Keywords: Wronskian,Linear differential equations,Method of variation of parameters Abstract: If for an arbitrary 3th order linear differential equation, non-homogeneous, we know two solutions of its associated homogeneous equation (HE), then we show how to determine the third solution of HE and the particular solution of the original equation.
