How do you approximate the value 'M' for the error bound formula for the Trapezoid Rule of a function that the derivative cannot be found? Error Bound Formula: http://archives.math.utk.edu/visual.calculus/4/approx.2/index.html I'm trying to figure out the value of n to get erf(1.00)...

http://en.wikipedia.org/wiki/Error_function If you have erf(1.00) and are asked to solve for the approximate value by using the trapezoid rule with n=6, how would you go about doing so? Since the function is erf(x) the 'x' goes into the limits of integration but a 't' is used as a variable...
