Exercise 7G 1. 2. Given the boundary value problem: y" = e, for 0≤x≤1, with the boundary conditions, y(0) = 0 and y(1) = 0. (a) Derive the system of linear equations (in matrix-form) using finite-difference method for this problem by taking h= Ax = 0.25. (b) Estimate the values of y(x) at x = 0.25, 0.5, and 0.75 by Thomas algorithm method or calculator. Given the boundary-value problem y" = 12 x², for 1≤x≤2, with the boundary conditions, y(1) = 2 and y(2) = 17. (a) Derive the system of linear equations (in matrix-form) using finite-difference method for this problem by taking h = Ax = 0.2. (b) Estimate the values of y(x) at x = 1.2, 1.4, 1.6, and 1.8 by Thomas algorithm. Answers to Exercise 7G 1.
