GG/OCN 312: Geomathematics

Instructor: Garrett Apuzen-Ito (gito@hawaii.edu, POST 810)

T.A.: Elise Rumf (rumpf@higp.hawaii.edu)

Prerequisites: MATH 242 or consent

Required Textbook: Advanced Engineering Mathematics by Michael. D. Greenberg

 

Overview and Objectives:

The main objective of this class is to familiarize students with a number of mathematical concepts that are used heavily in science and engineering.  Through a combination of lectures and lots of practice during homework assignments you will develop the knowledge and proficiency in using a variety of mathematical tools needed for future coursework and careers in Earth Sciences, Ocean Sciences, and Engineering.

 

Class format

The class meets 9:30 am – 10:20 pm, MWF, POST 703.  The lectures will introduce concepts and present methods needed to do the homework sets. 

 

RECITATION SESSIONS Recitation sessions are 1 hr on Wed. 11:30, 1:30, & 4:30 and Thu 4:30 to answer questions about lecture and/or homework.  These sessions are not required but highly recommended as most of you will find them very helpful in for doing the homework.

 

grading 

40% homework, 15% midterm 1, 15% midterm 2, 30% final. 

 

READING

You will have reading and homework assignments each week.  Reading will be reinforced by lectures and will provide formal background to do the problem sets.

“In high school mathematics courses most students are accustomed to tackling their homework problems first, out of impatience to have the whole burdensome task over and done with as soon as possible.  These students read the explanations in the text only as a last resort, if at all.  This is a grotesque reversal of reasonable procedure, and makes about as much sense as trying to put on one’s shoes before one’s socks.  I suggest that students should read the text first, and when this has been thoroughly assimilated, then and only then turn to the homework problems.  After all, the purpose of these problems is to nail down the ideas and methods described and illustrated in text” – George F. Simmons, Calculus with Analytic Geometry

 

HOMEWORK

Homework is due on Fridays at 3:30 p.m. at the instructor’s office (POST 810).  If it’s not in by 3:30 it doesn’t count.  Only under extenuating circumstances can homework be turned in late and only if permission is obtained from Prof. Ito prior to the due date.
