Hi, in my numerical methods i missed my lecture and i am currently unable to obtain the solution of a problem from my lecturer. How many points should be used to compute the integral exp(-x^2) over the interval [0,1] with an error at most 5x10^-5? At the end of the previous lecture we where given a formula for the the error over the interval [b,a] I-T=-1/12(b-a)h^2f''(w) + O(h^2). Where f''(w) is the maximum second order derivative at a point w in the range. Any help would be appreciated.(adsbygoogle = window.adsbygoogle || []).push({});

Also how would i do the same calculation for Simpsons Rule?

Thanks
