Abstract:In this paper, we study the existence and location of turning points of the convex solutions for a certain class of the ordinary differential equations subject to the Dirichlet boundary conditions. We propose a practical and effective method for calculating the lower and upper bounds of turning point location.
“…In this section we state a theorem which is the main result of article concerning the estimate of location of a turning point x T P, of solution y of the problem (1), (2). Theorem 4.1 (compare with [6]). Let the assumptions of Theorem 3.1 are fulfilled and let there exist Riemann integrable functions g L and g U over [a, b]…”

This article deals with the design of effective numerical scheme for solving three point boundary value problem for second-order nonlinear singularly perturbed differential equations with initial conditions. The obtained system of nonlinear algebraic equations is solved by Newthon-Raphson method in MATLAB. It also verifies the convergence of approximate solutions of an original problem to the solution of reduced problem.
