## Course summary

This a second course in calculus covering methods and
applications of integration; enrolled students should
have already passed MAT 125 or had an appropriate
score on the Mathematics Department placement exam.
We will cover the definitions of definite and indefinite
integrals, the fundamental theorem of calculus, methods
of explicitly evaluating integrals, methods of numerically
estimating integrals, applications to computing areas,
volumes, arclengths and other applications, parametric
equations and calculus with polar coordinates.

A description of MAT 125 and links to webpages from previous
semesters can be found here . If you need to review limits and
derivatives, look at Chapters 1-4 of
Volume 1 of our current textbook, that can be downloaded from
Open Stax Calculus Vol I
A Lumen OHM course giving review problems of MAT 125 material can
be found
here with course ID 44639 and enrollment
key 'MAT 125 review'. This is not required and is only
made available in case you want to review any MAT 125 topics
on your own.

## Textbook

The textbook is Volume 2 of Calculus by Open Stax at
Rice University. This is a free online textbook that can be
downloaded from
the link on this page .

If there is a problem with the above link, two alternatives are:
Calculus, Volume 2 and
here.

If you prefer smaller files, here are the individual chapters we
plan to cover:
Chapter 1 ,
Chapter 2 ,
Chapter 3 ,
Chapter 7 .
Links to individual sections of the text are given below in
the lecture schedule.

## In-person versus online recitation sections

In order to accomodate students who cannot come to campus
regularly, MAT 126 is taught in two lectures, one with
in-person recitations and one with online recitations.
All Lecture 1 recitations are in-person and taught by Prof. Bishop; students who may attend these regularly have the possibility enroll in the other lecture and
one of its recitations.
Lecture 2 of MAT 126 is entirely taught online for lectures and recitations.
The two MAT 126 lectures will have similar schedules and exams,
and we will try to make it possible for students to view both
lectures if they wish, but for grading will be important to regularly
attend the lecture and recitation that you are enrolled in.

As per current
university requirements for large classes, the twice-a-week
lectures will be online via Zoom, but the once-a-week
recitation sections led by teaching assistants (TAs), will meet
in-person for Lecture 1, online for Lecture 2. Midterms and weekly quizzes will be
administered in recitation for Lecture 1, but they will be done during lecture for Lecture 2.
Times are locations are listed below, as well
as contact information for the TAs.

## Technical requirements

Since all lectures are presented via Zoom, all students will need a device with this software installed. Links to the Zoom lectures are provided in Blackboard.

We will use Lumen OHM for homework, so you will need a device with a web browser that can connect to the Stony Brook Blackboard site to access homework. You will also need to access your Stony Brook Google email to receive occasional emailed announcements (these will also appear in the Blackboard announcements for the course).

## Special situations regarding online issues

With the online course, sometimes not everything can go right everytime when it comes to electronics and internet based issues. Here is what can happen if something shuts down.

-If my connection drops, I will try to reconnect and two cases happen. If I can reconnect, then I will try to resume where I left. Otherwise, if it fails for 15 minutes, then the class is canceled, and I will send an email with the remaining prerecorded remaining of the lecture and will reconvene a special zoom office hour where I go through the missing content.

-If it happens that your connection dropped, then the course (which is automatically recorded) is always available online on Blackboard and I am available by appointment to discuss the content you missed.

## Grades

Grades will be based on 5 types of evaluation:

** Lumen OHM problems sets (20%):**
Lumen provides a free (to the student) Online Homework Management
system that generates random variations of problems selected by
the instructor and grades them automatically.
You do NOT need to sign up for an Lumen OHM account; the
assignments should be visible to you through Blackboard (in fact,
if you access the homework from an individually set up Lumen
OHM account, and not through Blackboard, your
homework grades may not recorded in Blackboard correctly).
We will drop the two lowest homework grades.

Assignments in Lumen OHM are automatically graded by the system, so
you will see the results right away. You will be allowed multiple
attempts to do each problem without a penalty, and to ask for an
alternate version of the problem instead. The due dates of these
will be the same for everyone in MAT 126, regardless of section, usually
on Friday of the week following the week when the relevant material
is presented in lecture (but you are encouraged to do it earlier, and
even try to do them as soon as we covered the material in class).
In general, the Lumen OHM problems only give credit for
a correct answer in the correct form; no partial credit.

** Class participation (5%):** There will be assignments
in Lumen OHM to be done during lectures: many of these problems
I will do as examples and you simply have to enter my answer
into the assignment. A few I will leave for you to try during
lecture, to ask me questions about and complete after class, if
necessary. You will have 24 hours to complete these problems.

** Weekly quizzes on Monday (20%, drop worst 2 of 9):**
I
will give short (about 20 minutes) quizzes at the end of most
Monday lectures on non-exam weeks.
Quizzes will be given using Lumen OHM.
Details will be provided at the beginning of the semester.
We will accomodate students who cannot attend the quiz on Monday. The worst two quiz grades will
be dropped and missed quizzes will count among these.

There are no Monday quizzes in weeks 5, 9, and during Week 13, there will be a quiz on Monday and an Exam on Wednesday.

** Exams in Lecture (3 Online exams, 15% each, 45% total):**
There will be three exams taking up an entire lecture
in weeks 5, 9 and 13 on Wednesday.
These will cover roughly Chapters 1, 2 and 3
respectively; the exact sections covered on each
exam are given in the lecture schedule below.

** Online final exam (10%):** There will be a cumulative
online final exam on all the sections of textbook covered
in the class. It will be given in the Lumen OHM system,
the same system used for the online homework.
Some form of online proctoring will be used.

## Blackboard

Blackboard is the Stony Brook University class management system. Your homework, quiz and exam grades will be posted here. Letter grades for the course are posted in the Solar System. I will occasionally post announcements in Blackboard; you should receive email notifications whenever this occurs. Homework assignments and the online final can be accessed through your Blackboard account. Also links to the lectures via Zoom.

## Solar System

Solar System is the Stony Brook University administrative management system (registration, bills,...). It is not used for classes, except to post letter grades at the end of the semester..

## Stony Brook Gmail

Check your firstname.lastname@stonybrook.edu email here.

## Stony Brook Virtual SINC Site

Late in the course I expect to demonstrate software from the Virtual Sinc Site. This gives you access to various software packages on a university license, such as Mathematica and Matlab. These systems, among others, are can be used to compute some difficult integrals symbolically (Section 3.5 of the text) and most numerically (Section 3.6). I plan to demonstrate how they are used in lecture, but I won't require their use on assessments. Using the virtual Sinc Site requires downloading the Citrix receiver software (you will be prompted). Even though we won't need to use the Virtual Sinc Site much in this class, it is good idea to make sure you can access it for future classes.

## Math Learning Center (MLC)

MLC webpage.

Normally, this is a room in the basement (SL level) of the Math Tower where
you can go for face-to-face help with teaching assistants and faculty
(not necessarily your own instructors). However, for Fall 2020 the
MLC will be entirely online. To use the MLC click this
link for MLC webpage.
When there are tutors online, there is a zoom link to the session
for that tutor.
The zoom sessions are set up so that the student needs to be
authenticated, usually with SBU netid,
and the tutor is supposed to use the waiting room
so that they get admitted "on demand" -- typically one student at a time.
Each MAT 126 TA is supposed to hold
three office hours each week, two of which take place in MLC.
You may either seek out your own TA, or get help from whoever is
available at the moment (however, TAs from other classes might not have
access to MAT 126 textbook or assignments, so you will have to
describe the problem to them, or show it to them with the share-screen
feature).

## Zoom

You can download Zoom here, if you do not already have it installed on your computer. Access to Zoom lectures and recitations will be provided through your Blackboard account.

## Changes to the original lecture and recitation days-times-places

If you registered for MAT 126 in the Spring, then your original section choice may have been canceled or moved, so please make sure you know the new place and time of your lecture and recitation. For your convenience, all MAT 126 recitation times, places and TAs are listed below. Although both lectures and all recitations should cover the same material, attending the correct meetings is important to make sure your participation and assessments are recorded accurately.**Lecture 1 (lecturer is Prof. Bishop): TuTh 9:45am-11:05am.**online lectures - access through Blackboard.

## Lecture Schedule

For each week I list sections of the text we plan to cover that week. When two sections are listed, we will generally do one per lecture. When there are three listed, the middle topic will often straddle both lectures.Online homework on each week's sections will be assigned in Lumen OHM and due for everyone at the end of the following week. However, it is

**very highly**recommended that you to complete the assignment by the time of your recitation class.

**Every Monday, the lecture will end with a short 10-15 minute quiz**on the material from the previous week, so it is to your advantage to have done all the problems and ask for help during the recitation, before the quiz.
