By means of the software Maple, we obtain solutions of the problems of the nonlinear dynamics of a solid body with fixed point (a spherical pendulum) under the action of forces between a magnetic dipole of the pendulum and ...
A solution of the Cauchy problem and phase portraits based on Maple-software procedures for a system of non-linear differential equations of the 12-th order describing the free magnetic dipole dynamics in the field of an ...
A nonlinear system of ordinal differential equations of the 18-th order is derived, the Cauchy problem is solved, and phase portraits are constructed by means of the Maple-software.
