Given the Lagrange polynomial with the table:
Find for , the actual error and the bound of error for the function
Ok now I've found and I'm approximating which from my polyinomial is 17.877155 (close enough I think).
But I don't know how to find the bound of error using the remainder term! Anyone please show me the steps at least. Thanks in advance.
