Homework 5 1) a. 0.627805 b. 0.620609 c. 0.044256 d. 0.044935 e. 0.620609 2) A) a. 3.058629 b. 4.978098 c. 8.034739 B) The approximations will be less than the actual value because the function is increasing on the given interval and the function uses a left hand approximation. The errors resulting from beginning with the left hand endpoint will cause the approximation to be less than the integral’s actual value. C) The values are different because of the discrepancy in the number of rectangles/intervals used. The sum of the two integrals has a 1000 intervals in each term while the single interval only has 1000. So the values will not be the same as a result of the difference in error in both expressions. D) To eliminate the difference mentioned in part C one would have to adjust the number of intervals used in the second term (overall integral from 1 to 3) to 2000. Thus both expressions would contain the same degree of accuracy and result in the same output. 3) A) 8.042693 B) The actual value is less than the right hand rule approximation. This happens because

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
