Term II (201420) – Faculty/Course Evaluations for McNichols Courses – Starts Tuesday, April 15, 2014

The faculty/course evaluation process is important in providing feedback for continuous improvement.

The course evaluation site is https://www.udmercy.edu/evaluate/

The open window for completion of faculty/course evaluations is scheduled based upon the length of the course and the school/college in which the course is offered. Thus, if you are taking a course taught by the College of Liberal Arts and Education and a course taught by the School of Business, the open window for evaluation will be different for both courses.

College of Liberal Arts and Education, School of Architecture and College of Health Professions/McAuley School of Nursing Courses

Faculty/Course evaluations for the standard 14 week course sections may be completed during “dead” week and Final Exam week between Tuesday, April 15, 2014 and Monday, April 28, 2014.

College of Engineering & Science, School of Business and ALL other programs Faculty/Course evaluations for the standard 14 week course sections may be completed during “dead” week between Tuesday, April 15, 2014 and Monday, April 21, 2014.

Students may access the system from any internet connected computer whether on or off campus. For those students who prefer to use a University computer, systems are available in the ITS labs across the McNichols campus. All evaluations are completely anonymous.

If you are unable to complete your online evaluation(s) due to technical reasons, please contact the Helpdesk with details ASAP. All evals must be in the system by the published end-date. If contacting the Helpdesk afterhours, please leave a voice-mail at 313.993.1500 or e-mail at helpdesk or submit a ticket into the http://helpdesk.udmercy.edu system and someone will follow up with you the next business day.

Feedback for Exam 3

Feedback for Exam 3- MTH 1120- W14

For problem 2.3, it is better to rewrite ln(sqrt(8x-13)) as 1/2 ln(8x-13) by using the properties of logarithms. Otherwise, the problem is too long.

For problems 3 and 4, use the quadratic formula x=(-b+-sqrt(b^2-4ac))/2a.

For problem 4, find the critical points by factoring. Also, when you make the table to decide concavity, use the inflection points, not the crtical points.

In problem 3, the fixed cost is $400, not -$400.
