MATH 139 Midterm: MATH 139 McGill Examf02
Math 106 Fall 2013
Final Exam (75 points)
Name:
Show all your work to receive full credit for a problem and keep your written answers
brief and clear. Points will be taken off if you do not show how you arrived at your
answer, even if the final answer is correct.
Do not use the calculator integral function. Whenever possible, find the exact values
of integrals by finding antiderivatives or using the table of integrals. When you use a
formula from the table of integrals, mention the formula number and the value(s) of
any constant(s) that you may need.
Give exact answers. If needed, round off your answers to four decimal places.
There are twelve questions on five pages. Questions are printed on both sides of a
page.
You may use any of the following facts:

Show all your work to receive full credit for a problem and keep your written answers brief and clear. Points will be taken o if you do not show how you arrived at your answer, even if the nal answer is correct. Whenever possible, nd the exact values of integrals by nding antiderivatives or using the table of integrals. When you use a formula from the table of integrals, mention the formula number and the value(s) of any constant(s) that you may need. If needed, round o your answers to four decimal places. Questions are printed on both sides of a page. You may use any of the following facts: Arclength=z b a q1 + (f (x))2 dx.
