MTH 453/553 – Homework 2 1. Consider the following two point boundary value problem: u′′(x) = − sin(x) u(0)=0, u(π)=π (a) Using the second order, centered finite difference scheme discussed in class, discretze this two point boundary value problem. What is the resulting system of linear equations? (b) Compute the error constants in the truncation
