## MyLab - Online Homework

Students are required to purchase access to MyLab Math to complete the online homework, and possibly quizzes and exams. The MyLab assignments are similar to the exercises in the official list of HW exercises. (The official HW exercises are not handed in for grading but instead form a significant, but not exhaustive, portion of your study guide for the course.) Each assignment will have a specific due date set by the professor, and these assignments must be completed online.

How to use MyLab properly:
If you take shortcuts like trying to find answers to MyLab problems from various "homework help" web services without solving all of the problems yourself in their entirety, then your performance on exams will suffer. Instead, use the built-in help tools within MyLab. This online homework exists primarily to give you feedback on your ability to calculate correct answers at early stages of the learning process. The homework is not intended to measure your mastery of the material; only the midterm exams and final exam measure mastery. Without doing well on the exams, it is impossible to pass the course, even with a perfect score on the homework. So be sure to take full advantage of MyLab to get as much feedback as possible on your problem-solving skills.

#### Getting started with MyLab:

• You will be able to access your MyLab course directly through your Canvas site for Math 251.
• In your Canvas site, navigate to MyLab and Mastering and follow the on-screen instructions to create a Pearson account (or link an existing Pearson account) to your Canvas account.
• You will automatically be enrolled in the MyLab course.
• If you switch to a different section of Math 251, you can enroll in your new section's MyLab course by following these same instructions.

#### Student support for MyLab:

• System Requirements
MyLab works on a series of pop-up screens. You MUST enable pop-ups when working in MyLab. For help on how to do this, as well as make sure your browser is up to date, use the link above.
• How to Use MyLab on a Mobile Device
This video shows you how to set up your mobile device with any necessary browser add-ons and apps to use MyLab properly.
• Pearson Support Database
Use the above link to search Pearson's database for support topics (e.g., resetting password).
• Contact Support
Use the above link to contact technical support. Fill out the required form and you will be immediately connected to a support agent based on your issue.
• Pearson sales representative: melissa.blum@pearson.com
Melissa Blum is our Pearson Sales representative. If you are having technical issues, please first contact Technical Support. If you are still having issues after contacting Technical Support, please email Melissa Blum with the Incident Number you received from working with Technical Support. You must have an Incident Number for Melissa to be able to help.

• MyLab is an interactive, online homework system. The assignments follow the lecture topics.
• Questions are algorithmically generated to give each student their own random versions of the questions.
• After entering an incorrect answer, students are given helpful feedback and hints. Most exercises will also include learning aids, such as guided solutions and sample problems.
• You have three attempts to get an answer correct. If you use all three attempts, you will be told the correct answer and given a new, random version of the same problem. There is no limit to the number of versions of a particular problem you can be given. So you are strongly encouraged to work on a problem until you get the correct answer. There is no penalty for the number of attempts taken.

## Matlab Computer Labs

We will have some computer labs to show how technology facilitates the learning of certain calculus concepts. These were primarily designed for Matlab, since you can use the Rutgers license to download it for free. However, you may also use Maple or Mathematica to work on these assignmets. More information about them will be given during at the beginning of the Spring Semester.

## Solutions to practice exams and additional documents

Extra problems  : if you have finished working on the practice exams and additional review material provided by your instructor, you may want to check this list of problems if you want to do additional practice problems. Some of these are more conceptual in nature, so they may be useful to enhance your understanding of the course material.

Information on the February 7 Short Exam

Short Exam Guide

Respondus Sol

Practice 1 Feb 7 Sol

Practice 2 for Feb 7 solution

Dear students,

Here is the information you need to know about the upcoming short exam.

• Date of the exam: February 7.
• Duration of the exam:45 minutes.
• Time window to access the exam: 9:20 pm -10:20 pm (EDT).
• This exam will be online, and will consist of two non-upload and two upload problems.
• For this exam we will be using Respondus. Typically it takes between 5 and 10 minutes for the authentication process to be completed before you can start working on the exam.
• For example, if you finish being authenticated by Respondus at 9:30 pm, then you would be done with the short exam at 10:15 pm, and then you would have 20 minutes (until 10:35 pm) to upload your work to the canvas site.
• We encourage everyone to start the exam process as soon as possible and email your professor immediately if you are running into any technological issues (losing access to the exam because of poor internet connectivity, etc).
• Personal Note Sheet: Any formula listed / mentioned in the study guide "short-exam-guide" (mentioned later in this announcement) that you find difficult to memorize may be written down by hand on your personal "note sheet''.   Your note sheet can be at most a two-sided piece of paper, and no other exam materials may be accessed while you are taking the exam.You must show both sides of your note sheet to the camera during the Respondus login process.
• Other things not allowed: Phones, calculators, computer algebra systems like Wolfram Alpha, you cannot give or receive help from anyone else, nor “check your answers” on a calculator, online, or with anyone.  If you do not follow these rules, you will risk an Academic Integrity Violation (http://nbacademicintegrity.rutgers.edu/home/academic-integrity-policy/
 Academic Integrity Policy - New Brunswick Rutgers University | Division of Student Affairs – New Brunswick. Search This Website. Academic Integrity Policy; For Instructors and AIFs nbacademicintegrity.rutgers.edu
), which may lead to a zero on the test.
• Late submissions to the exam questions will not be accepted, and will result in you not obtaining any points on that problem, even if the solution on mylab is correct. Emailed submissions will not be accepted.
• If you have been approved (by ODS) for extra time, you will receive accommodations during the exam.You must provide your own professor the relevant ODS documentation as soon as possible.
• Students who are in time zones for which the exam time is impractical, or who have an unavoidable conflict/emergency may be able to take a makeup, provided you email your own professor as soon as possible.

As of now, you should now be able to access two practice exams for the February 7  Short Exam  through the MyLab site of your individual course. The assignments are called "Practice 1 for Feb 7 Short Exam” , "Practice 2 for Feb 7 Short Exam"

These practice exams will not be graded, so you can practice it as many times as you want, and at any time before the midterm. Solutions for these practice exams will be posted on February 1st at the beginning of this announcement.

On this website you will also find a study guide for this exam, called short-exam-guide.

Likewise, on this website you will find solutions to the respondus assignment "Respondus Practice Sp 22"Please complete this assignment a few days before the date of the short exam, so that you become familiar with the Respondus environment.

The sections of the book for the February 7 short exam are:

• Section 12.1: Three-Dimensional Coordinate Systems
• Section 12.2: Vectors
• Section 12.3: The Dot Product
• Section 12.4: The Cross Product
• Section 12.5: Lines and Planes in Space
• Section 12.6: Cylinders and Quadric Surfaces

Here are some useful things to be aware of:

• The practice exams and the February 7 short exam consists of4 questions each.
• Nature of the Uploaded Work: the uploaded work should not be interpreted as "scratch work". Rather, it is supposed to be a detailed solution to the problem of the exam (similar to the one you would write if the exam were in person).
• The practice exams do not include every type of possible question you might expect to see on the exam. Therefore, you are still encouraged to work out the MyLab assignments and any other material you find useful which has been provided by your professor.
• As you will see on the practice exam, the last two problems have the instructions:

Important: you need to upload your work for this problem to the Canvas site. Remember that you have 20 minutes after submitting the MyLab exam to do the upload”

• For the practice exams there will be no need to do such an upload, but we wrote the statement to give you an idea of how the upload questions will look like on the actual exam.

Sincerely,

Math 251 professors

Dear Math 251 Student,

The Math 251 instructors have spent the days since Thursday's final exam grading the final exam and compiling the course grades.  Many of your instructors have posted the final exam grades and have submitted the course grades for their sections.  If you have not received your final course grade from WebReg and/or "unofficial transcript site", you will be able to see them very soon.

The final exam won't be shown on Gradescope. If you want to see your final exam you must schedule an appointment with your instructor sometime after May 28.

Your course grade is determined via the table posted on the department website

Classwork                                                         100 pts               [20% of grade]

Short Exam and Midterms [4]                           230  pts              [46% of grade]

Final                                                                  170 pts                [34 % of grade]

The number of A's, B+'s, B's, etc., that an instructor can give as the letter grade for the course are determined by a committee of instructors after grading is done.

Once each instructor determined the A’s, B+’s, B's, etc., they could assign in each class, the course score was computed using the weights mentioned previously.

For example, if the instructor was allowed to give 5 A’s in their course, the students with the top 5 course scores receive the A’s, and so on.

We wish you a happy summer and hope that you stay safe and healthy during the upcoming months.

Sincerely,

251 instructors.
