Title: More Integrals + trapezoidal rule - Multiple Choice Post by: calcourse on May 12, 2013 1. find integral [0,786] xsin^2(x) dx
a. 0.393 b. 2.906 c. 0.0831 d. -.607 e. -2.973 2.use the trapezoidal rule with n=4 to approximate int[2,3] (1)/(x-1)^2dx a. .5004 b. 2.5000 c. 0.5090 d. 1.7396 e. 2.5610 Title: Re: More Integrals + trapezoidal rule - Multiple Choice Post by: bio_man on May 12, 2013 For #1, those limits are incorrect; are you sure it's 0 to 786?
