IfWhat would happen if I wrote a finite-difference code evaluated at a point where the function doesn't have an explicit formula, and we don't know how smooth it isisn't differentiable, can we use finite differences to compute its derivativeanalytically? Would that make sense, or do people use finite differences only for functions that have explicit formulas and is also known
I'm trying to be differentiable / smooth enough?think analytically vs numerically.
Thanks,
