Class Schedule

 

Problems in green have been graded.

 

Each graded problem is worth 5 points, unless noted otherwise.

Correctly solved problems are marked with a checkmark; others are given the grade like 3/5, etc.

 

Unless stated otherwise all problems are due in one week.

Do not hand in problems for which there are solutions or answers in the book, unless told so explicitly here.

I will not remind you to hand in the problems – this is your choice and responsibility.

I will let you know what problems have been graded, if any, after the deadline.

 

Review I is on this Friday, Dec 13, 2007 Southwick 407 at 10 AM.

I will answer your questions during this review, like ``What is Jacobian?", or "How to compute the determinant", or `` What this [--] notation means", etc.

 

Review III is on Wednesday -- Photos

10 AM in the usual room

 

I will solve a couple of problems typical for the final.

 

Office Hours 2:30-3:45 PM (changed from 4 PM) on Monday and

 2:30-4:00 PM Wednesday

42, 44, 48 of 10.6;

For a cone described by the equation on page 846 find a section which is a parabola.

Hint:

1)      find a plane which is parallel to a line contained in the cone.

2)      find the equation of the section

3)      prove it is a parabola (by a change of variables, if needed)

 

For a higher grade for this problem work with parameters a and b. If this is difficult for you, do the same problem for some chosen values of a and b.
