MATH 6702 Math Methods in Applied Sciences II

Spring 2012

Tuesday 8:30-10:00, Wednesday 11:00-12:30 Brown room.

Professor Federico Bonetto

Office Hours: TW 10-11, room 215. 

Review of vector calculus and and its application to partial differential equations'

The text that will be used is:

Advanced Engineering Mathematics by Dennis G. Zill, Warren S. Wright, Jones & Bartlett Learning.

The syllabus can be found here.

There will be two midterm.

The exercise listed are for HW collection. I will collect them every two weeks and grade 2 or 3 exercises among the one assigned. 

The final grade will be based on the following rules: 45% final, 35% midterms, 20% HW. Curving will be done on the final result.
