Question details
Derive this central difference approximation please and state what A, u_ and f_ are.
-u(z) + u(x) u(0) 5x, -1, x E (0, 1), u(1)=1. = = Derive a central difference approximation to u on the grid ay = jh for j = 0, 1, . . . ,N and h = 1/N. Write down a linear system of equations of the form Au = f for u-[ui, u2, . . . , uN-1]T, where u is the central difference approximation to u(r
