As mentioned in class, sometimes we need to expand a derivative of a function and not just the function itself. Given one is interested in the second derivative of u at point j - 2, please write down the Taylor series expansion of the second derivative for around point j for the next 3 terms as well as the general nth extra term:
\( (u_{xx})_{j−2} = (u_{xx})_j \quad +? \)
\( (u_{xx})_{j−2} = (u_{xx})_j \quad +? \)
