## Abstract

Consider the problem:

$$y”(x) + f(x, y) = 0, \ \ x \in [0, 1], y(a) = \alpha, y(b) = \beta, a, b ∈ (0, 1),$$

which is not a two-point boundary value problem since \(a, b ∈ (0, 1)\).

It is possible to solve this problem by dividing it into the three problems: a two-point boundary value problem (BVP) on \([a, b]\) and two initial value problems (IVP), on \([0, a]\) and \([b, 1]\).

The aim of this work is to present a solution procedure based on pseudospectral collocation with Chebyshev extreme points combined with a Runge-Kutta method. Finally, some numerical examples are given.
