Taylor Table skewed method

Objective: Central difference scheme From Taylor series Taking four point from the base LHS 2 point RHS side two point (d^2 u)/(dx^2 )=af(x-2)+bf(x-1)+cf(x)+df(x+1)+ef(x+2) Find the vale of a b c d e skewed RHS For second point (i-2) f(x-2*dx)=f(x)-f^\' (x) (2*dx)+f^\'\' (x) (4dx^2)/2!-f^\'\'\' (x) (8dx^3)/3!+f^iv (x) (16dx^4)/4!…
