Question about error theorem for simpsons rule

  1. Dec 11, 2005 #1
    it is:
    E=|I-Sn|>= (k4 (b-a)^2 )/ (180 n^4)

    I know what all of the parameters mean except I, what is it again? It cant be the integral as thats why were using simpsons rule so is it a guess or?:blushing:

    It is, in fact, the integral. Just because you don't know what it is doesn't mean you can't write an equation about it. S_n is the "n" guess.
