Math 141 Final Exam

Math 141/6380, Due by 11:59pm, Sunday, March 4, 2018

This is an open-book exam. You may refer to your text and other course materials as you work on the exam, and you may use a calculator. You must complete the exam individually. Neither collaboration nor consultation with others is allowed.

Suggestions about how to approach this Final Exam:

  1. Print out a copy of the Final Exam and solve any problems that you can using pencil and paper.
  2. Review the eBook sections associated with any problems you could not solve.
  3. Complete the remaining problems to the best of your ability. Even if you cannot come to a final solution, you should show me what you do know so that you have the opportunity for partial credit.
  4. Review your work. Check for errors. Make sure you have included units where appropriate, and explanations when required by the instructions.
  5. When you are satisfied, type in your solutions (extend space if needed) or, if you have the facilities, you can scan your hand written work or take photos with your camera. Make sure that your submission is readable.
  6. Submit your work in the associated LEO assignment.

Unless the problem explicitly states otherwise, work must be shown for every answer. Any answer, even if “correct” but lacking work, will NOT receive full credit and may receive NO credit!

Please submit the exam as an attachment in any readable formats such as scanned or photo copy before or on Sunday, March 4. No late exam will be accepted. No make-up final exam will be arranged. Solution keys for the Final Exam will NOT be released.
