Homework Due Next Week....(nothing gets done except for the last moment)

You have a lot of homework to do for next week....from which I get the picture of desperate students desperately trying to finish their webwork all night on Thursday night....and not being happy with their success.  Accordingly, let's motivate you to spread this out a little bit by making half the homework due next Tuesday, and the other half due on Friday.

Webwork section 12.2 and section 12.3 due Tuesday April 1 at 2pm.
Webwork section 12.4 and section 12.5 due Friday April 4 at 8:00am

The Exam....

Will cover all of chapter 11 and sections 12.1 and 12.2.

There will be review sessions for Test 2 on 3/18/2014 and 3/19/2014, 6-7PM in Hayden L62.

I will have pretest office hours Noon-1PM on Tuesday and Thursday, and 2-3PM on Wednesday.

Webwork section 11.7 and section 12.1

Webwork Question

Professor Taylor,
For this hill-climbing problem I have tried computing the gradient and
making it into a positive unit vector, but I keep getting the wrong answer.
How do I do this problem?

Thanks,

Since you don't specify, I guess you mean a problem like this one.18:

***************************************************

The direction of maximal increase is in the direction of the gradient.  Since grad(z)=-0.18i-0.08j, the unit vector in this direction is u=grad(z)/|grad(z)|=(-0.18i-0.08j)/√(0.18^2+0.08^2)=-0.914i-0.406j.  The angle above the horizon can be obtained from the dot product of u with a ±i.

Most Recent Scores as of 3/5/14 & estimated grade

These are the most recent homework, quiz and exam scores as of 3/5/14.  Also included is an estimated current course grade--this is an estimated grade only, since course policy says that the grade is to be based on 50% midterms, 25% final, 15% webwork and 10% quizzes.  Since you haven't taken the final yet, I am instead estimating the grade as 75% midterm, 15% webwork and 10% quizzes.
