WitrynaIntroduction. Take the second order differential equation. ad2y dx2 + bdy dx + cy = 0. Where a, b, c are constants. Then suppose that y = u and y = v are distinct solutions of the differential equation. In other words. ad2u dx2 + bdu dx + cu = 0 and ad2v dx2 + bdv dx + cv = 0. The general solution to the differential equation is then. WitrynaThe general solution for linear differential equations with constant complex coefficients is constructed in the same way. First we write the characteristic equation: Determine the roots of the equation: Calculate separately the square root of the imaginary unit. It is convenient to represent the number in trigonometric form:
