A course of differential equations and variational calculus. 7th edition. Romanko V.K.

The manual sets out the basics of the theory of ordinary differential equations, equations in private derivatives of the first order and variational calculus. Along with the presentation of the traditional sections of the course of ordinary differential equations, the book also considers some non -traditional issues (boundary tasks, equations with a small parameter, nonlinear equations in private derivatives of the first order, variational task of the wander, etc.). Numerous examples illustrate the theoretical provisions under consideration. For students of higher educational institutions.
