Homework

Please change problem 24 in section 13.8 so that we compute the flux of the vector field <2x,2y,z² and not the surface integral as given. We do not do scalar surface integrals except the surface area in this course.
In problem 38 of section 11.8, there is a typo in the solution: the x-value for the minimum is put as (1/3)(50-10sqrt(3)), when it should be (1/3)(50-10sqrt(10)). Thanks to Yunhan Chen.
In section 11.4, avoid differentials. It is an old fashioned term. In order to estimate a function near a point, where you know the value, evaluate the linearized function. This is the linear approximation.
In the baseball problem 26 of section 10.4, the result is close. Please use g = 3.2808399 * 9.80665 = 32.174 ft/sec² to determine whether it is a homerun or not.

Homework is due at the beginning of class. We do not accept electronic HW submission. If you do the homework with a word processor like LateX, print it out and submit the paper.
Please staple your homework.
No late homework accepted but will delete the least 3 scores for MWF sections and 2 for TTh sections. Reserve these 3 "Joker" cards for emergencies.
Collaborations are welcome however you must turn in your own copy and list on it the names of your collaborators.
Similarly, acknowledge the use of Mathematica. If you use Mathematica, nevertheless, write down all steps of your computation or print out the Mathematica notebook, you authored.
If you can not turn in your homework because of a religious holiday like Yom Kipur, turn it in earlier or give it to a friend to turn it in.

Please write legibly and indicate clearly, where a new problem starts.
Try to keep the problems in order.
Use words to explain your work, if necessary. Show your work. Answers without explanations are given zero points.
If unable to finish a problem, indicate where you are stuck. This will help us to give partial credit.
Please inform about typos, misprints. We state here corrections to the in class distributed texts as well as to the posted solutions. Each hint gives you a bonus point. The texts posted here are corrected.
(+Sol) means solutions have been posted.
Homework scores from individual sections will be adjusted in the end because different graders grade each section.

MQC information Sunday through Thursday nights, 8:30 - 10:30 p.m., starting September 23 and ending December 15. The MQC will be closed for holidays on October 12, November 10, November 26 and November 27. MQC times: Sunday nights, in SC 112; on Monday-Thursday nights, in SC 222.

Grading: Each of the 5 problems assigned per unit is worth 10 points. Course assistants are encouraged to grade interpolating the following rubric:

10 Points. Work is completely accurate and essentially perfect. Work is thoroughly developed, neat, and easy to read. Complete sentences are used where appropriate.
5-9 Points. Work is good, but incompletely developed, hard to read or unexplained. Answers that are not explained may received 2 points even if correct. The work contains the right idea but is flawed.
3-5 Point. Work is sketchy. There is some correct work, but most of the work is incorrect.
0-3 Points. Work is minimal or non-existent. Solution is completely incorrect. Only the answer is given.
