MAT 126 
 Calculus B  
Fall 2021

MAT 126 is the second semester of the three-semester calculus sequence MAT 125/126/127. This is a continuation of MAT 125, covering integral calculus. Topics covered include: the fundamental theorem, symbolic and numeric methods of integration, area under a curve, volume, applications such as work and probability, complex numbers. Knowledge of this subject matter is essential for those wishing to pursue studies in mathematics, the physical sciences, economics, engineering, and a host of other fields. A good grasp of differentiation is assumed at the outset.

Prerequisite: to take this course you must have received a grade of C or higher in MAT 125 or 131 or 141 or AMS 151, or at least level 6 on the Mathematics Placement Examination.
Textbook: Calculus Volume 2, by E. Herman & G. Strang, Open Stax at Rice University.

This is a free online textbook that can be downloaded for from here. In this course we will cover Sections 1, 2, 3, and 7.

Homework: Each week homework will be assigned based on the material covered during that week. It will be due on Friday of the following week at 11:59pm; the only exceptions are Thanksgiving week and the final week of classes. See the homework web-page for a schedule. All homework assignments will be administered through the Lumen OHM online system.

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 a 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 be recorded in Blackboard correctly.

Multiple attempts are allowed for each problem without a penalty. In general, the Lumen OHM problems only give credit for a correct answer in the correct form; there is no partial credit. Since the assignements are automatically graded by the system, you will see the results right away.

Access Lumen OHM Through Blackboard. There is a link to the class Lumen page in Blackboard, just underneath the Zoom link on left hand side. It is important to access homework through this link, so that Lumen knows to transfer your grades back to Blackboard. If you have used Lumen OHM before, you may have accessed it by first logging in and then using a Course ID and Enrollment Key, but we are not using this method for MAT 126 this Fall. Please let me know if you have any trouble seeing the Lumen content using the link in Blackboard.

Blackboard: This is the Stony Brook University class management system; the website link is here. Your homework assignments, as well as all grades will be posted there. Letter grades for the course are posted in the "Solar System" at the end of the course. Announcements will occasionally be posted in Blackboard. You should receive email notifications whenever this occurs.
Office Hours: The list of lecturers and teaching assistants, along with their office hours may be found at the course Staff link.
Calculators: The use of calculators will be forbidden on all exams in this course. You are free to use a calculator to check your solutions to homework problems, but you are urged not to turn your calculator into an unneeded electronic crutch.

There are good reasons for this policy. By not using a calculator, you will


Exam Schedule

Midterm I Thursday, September 30 8:15pm-9:35pm
Midterm II Thursday, November 4 8:15pm-9:35pm
Final Exam Thursday, December 9 2:15pm-5:00pm

By enrolling in this course, you are attesting to the fact
that you will be available for these exams at these times.

Grading: Your course grade will be computed based on your performance on examinations and homework, which will be weighted as follows:

Midterm I 22.5%
Midterm II 22.5% 
 Final Exam 35%
 Homework & Recitation  20%

No make-ups will be given for missed midterms. However, if you miss an exam because of documented circumstances beyond your control, then, at the discretion of the course coordinator, the relevant score may be dropped in computing your course grade.

A grade of Incomplete will be granted only if documented circumstances beyond your control prevent you from taking the final exam.

No late homework will be accepted. However, again if you miss a homework assignment due to documented circumstances beyond your control, then, at the discretion of the course coordinator, the relevant score may be dropped in computing your course grade.

Tutorial help is available in the Math Learning Center, located in the Math Tower basement, room S-240A. For more information click here. Tutors are available Monday - Friday, both in person and online via zoom. You do not need to make an appointment. The center provides free one-on-one tutoring in mathematics on a drop-in basis.
Videos of previous MAT 126 lectures by David Kahn may be found here. Additional video lectures for this course, as well as other calculus courses, are available here.
Peer Assisted Learning (PAL): The Academic Success and Tutoring Center will be hosting Peer Assisted Learning (PAL) for MAT 126 (PAL is also known as Supplemental Instruction). The MAT 126 lectures will have an assigned PAL leader, who is an undergraduate student. Each leader will attend all lecture meetings of their assigned class section and hold one weekly PAL session for students currently enrolled in the course. During their weekly PAL sessions, they will facilitate group activities in order to help students fully understand the application of the material that they are learning in the classroom. These sessions are not remedial in nature, are not tutoring, and do not take the place of the class. Instead they allow students a safe environment in which they can work together to delve into the material.

A video with further information concerning this program has been posted to YouTube by the organizers.

The two PAL leaders for MAT 126 are: Lauren Dawnkaski ( - attending Lecture 1; Kishon Ghosh ( - attending Lecture 2.

Student Accessibility Support Center Statement

If you have a physical, psychological, medical, or learning disability that may impact your course work, please contact the Student Accessibility Support Center, 128 ECC Building, (631) 632-6748, or at They will determine with you what accommodations are necessary and appropriate. All information and documentation is confidential.
Students who require assistance during emergency evacuation are encouraged to discuss their needs with their professors and the Student Accessibility Support Center. For procedures and information go to the following website: and search Fire Safety and Evacuation and Disabilities.

Academic Integrity Statement

Each student must pursue his or her academic goals honestly and be personally accountable for all submitted work. Representing another person's work as your own is always wrong. Faculty is required to report any suspected instances of academic dishonesty to the Academic Judiciary. Faculty in the Health Sciences Center (School of Health Technology & Management, Nursing, Social Welfare, Dental Medicine) and School of Medicine are required to follow their school-specific procedures. For more comprehensive information on academic integrity, including categories of academic dishonesty please refer to the academic judiciary website at

Critical Incident Management

Stony Brook University expects students to respect the rights, privileges, and property of other people. Faculty are required to report to the Office of Student Conduct and Community Standards any disruptive behavior that interrupts their ability to teach, compromises the safety of the learning environment, or inhibits students' ability to learn. Until/unless the latest COVID guidance is explicitly amended by SBU, during Fall 2021 "disruptive behavior" will include refusal to wear a mask during classes.
