integral(lower bound 1)(upper bound 5) 1/x^2 * dx; n=4

I need help finding the trapezoid error estimate of: integral(upper bound 5)(lower bound 1) 1/x^2 *dx; n=4

Thanks.(Worried)

I know that the formula is M(b-a)^3/12n^2 but I am having trouble understanding how to find M. - December 18th 2008, 11:08 PMmr fantastic
