Fall Term 2004
Test 1, October 1, 2004
•
This is an open notes test lasting 50 minutes.
•
There are two problems, divided into subsections. Problem 1 has 2 parts
and problem 2 has 4 parts. The points for each part are marked.
Bold
face letters denote vectors.
•
Begin each problem on a fresh sheet of paper. Use only one side of a
sheet of paper.
•
Put your name, the problem number, and the page number in the upper
right hand corner of
each
sheet.
•
To receive partial credit you must explain what you are doing. Carefully
labeled figures are important. Randomly scrawled equations aren't helpful.
•
Draw a box around important results.
