Systems of Linear Ordinary Differential Equations - Power Series Solutions solves boundary-value problems involving systems of linear ordinary differential equations of any order, with variable coefficients. The boundary conditions may also be equations involving the unknown functions and their derivatives, and the evaluation point may be different for each one. The solution produced is a continuous function in the form of finite power series of user-specified degree valid in the entire defined interval and expanded about a user-chosen center of expansion. The solution may be stored in a file which may be later read by a suitable program (like POWER AND TRIGONOMETRIC SERIES) to further study it to find roots, maxima and minima, derivatives, integral, graph. You may predefine constants. Handles a wide variety of functions, including trigonometric and hyperbolic functions. Results can be saved or printed. Includes a help file with instructions, example and methodology.
