Method for constructing solutions of linear ordinary differential equations with constant coefficients
V. V. Karachik Southern Ural State University, pr. Lenina 76, Chelyabinsk, 454080 Russia
Abstract:
For Cauchy problems involving linear differential equations with constant coefficients, a new method for constructing solutions without determining the roots of the characteristic equation is proposed. Formulas for the differentiation of the solution with respect to the equation coefficients are derived, and an approximate analytical solution is found.
Key words:
ordinary differential equations with constant coefficients, Cauchy problem, operator series, differentiation with respect to coefficients.
