Unformatted text preview: Z 1 sin( x 2 ) dx cannot be evaluated using the Fundamental Theorem of Calculus because sin( x 2 ) does not have an elementary antiderivative. (a) (10 pts) Approximate its value using Simpson±s method with n = 4 : Round your &nal answer to 4 decimal places. (b) (5 pts) You are given that & & & d 4 dx 4 sin( x 2 ) & & & ± 30 on the interval [0 ; 1] : Find an upper bound for the error in your approximation (ignoring round-o/ error).
