Hello to everyone
I have a question with many parts that i am needing to do.
(a)Derive the 2point formula, for numerical differentiation:
What is ?
(b) Derive the same formula as (b) witht 3points formula
(c) Discretisation error in (a) and (b) is
Prove that discretisation error for f'(1), where f(x) = exp(x) is
I am knowing that
but I cannot realise how to do these parts? Can someone please showing me how to prove?
