The Events Leading to the Brown v. Board of Education Case - Chapter 6 At this juncture the text divides into two tracks: one concerned with the qualitative theory of solutions to linear and nonlinear planar systems of differential equations and one mainly concerned with the development of higher dimensional linear algebra. We begin with a description of the differential equations chapters. This unit examines two particular classes of ordinary differential equations: dynamical systems and boundary-value problems. The investigation of boundary-value problems considers Sturm-Liouville eigenvalues problems and orthogonal polynomials, shooting and direct matrix methods for the numerical investigation of boundary-value problems and iterative matrix methods.

write 73,489 in expanded form - Brainly.com - The purpose of this course is to give a rigorous mathematical development of many classical topics in the study of ordinary differential equations and, more generally, dynamical systems. Throughout, we take a geometric point of view seeking qualitative information on solutions of nonlinear dynamical systems even when explicit solution formulas do not exist. We prove the existence of bounded and periodic solutions for planar systems by introducing a notion of lower and upper solutions which generalizes the classical one for scalar second order equations. The proof relies on phase plane analysis; after suitably modifying the nonlinearities, the Ważewski theory provides a solution which remains bounded in the future.
