Solve boundary value problem y" + xy = (x^3) -4/x , 1<x<2 , with boundary conditions 4y(1) +y'(10 = 0 , and 3y(2) + 2y'(2) = 0 , use h = 0.2 . Derive the system of linear equations in matrix by finite difference method ..

My answer is different with the ans provided . I have attached the ans given and also my working .

Which part of my working is wrong ? I spent the whole day looking at it , yet , still cant figure out which part is wrong ,

When i = 0 , i gt my ans = -14y0 + 50y1 = -3 , after simplification, my ans is

-0.56y0 + 2y1 = -0.12

But , the ans is -

**0.36**y0 + 2y1 = -0.12
