UNIVERSITY OF WINDSOR DEPARTMENT OF MATHEMATICS AND STATISTICS Integral Calculus MATH 1730-01 & MATH 1730-02 Final Exam Monday, April 25, 2022 Last name (PRINT): First name : Student No. : Section No. : Instructions : Download this exam to avoid any problem with internet while you are solving it. You can print this exam and write your solutions on it, or you can work on your own paper and put just the question number next to your solutions. In both cases make sure you have written your name and ID on your papers. Try to keep the questions in the same order when you scan your solutions. This exam has 12 questions. You have 180 minutes (3 hours). Read carefully and answer all questions. Show all your work to receive full credit . Give exact answers not the decimal approximations. Only non-programmable and non-graphic calculators are allowed. You must stop writing at 10:00 pm and must upload a single pdf file with your solved exam by 10:30 pm on Blackboard . Make sure the pdf is clear and your solutions can be seen clearly to avoid any confusion during marking. If your exam cannot be read, it will not be marked. Better to use pen or dark pencil if possible. You can submit your exam solutions once (you can save draft and check that it is fine before you submit). Make sure to check your submission is submitted and not in progress (you should see a yellow icon in My Grades if it is submitted). You are responsible for your submission, this means it is your responsibility to make sure your submission is on time and accurate (the file is correct and includes all pages, pages on email will not be accepted). Late submissions will not be accepted . Code of Conduct: This open book examination must be written without collaboration. While writing these you must not communicate with any other person and you must not consult the internet or any material other than the course textbook, lectures, your course notes, assignments, and any material posted on the course Blackboard pages. If there is any evidence of academic misconduct, we will file an allegation of misconduct according to Bylaw 31. All rights reserved.

4. (5) Find the number a such that the line x = a bisects the area under the curve y = 4 x 2 , where 1 x 4 Note. The line ‘bisects’ the region if the area of the portion of the region to the left of the line is equal to the area of the portion of the region to the right of the line.
