Course information.
Here you will find information about Lecture 04 of MAT127 - Calculus C. For general information about the course, including homework assignments and grading policy, see the MAT127 webpage. The course coordinator is Eugeny Gorsky ( The graders are Xiaolong Huan ( and Raquel Perales (

Instructor's email:

Instructor's office: 2-114, second floor of the Mathematics Building (click here for a map).

Location: Lecture 04 meets on Tuesdays and Thursdays from 5:20pm to 6:40pm at Library W4540 (click here for a map).

Textbook: Single Variable Calculus (Stony Brook University Edition) by James Stewart and these notes on Differential Equations.

Office hours.
My office hours are on Tuesdays from 7pm to 8pm at my office (2-114, second floor of the Math Building; don't you know where the Math Bld is? Click here for a map), and Mondays and Wednesdays from 2:45pm to 3:45pm at the MLC. Recall, however, that the MLC is a place for helping students; hence, you may come to the MLC any time you want and certainly you will find a tutor there to help you. If this schedule does not work for you, send me an email ( to set up an appointment.

Here are some important dates:
Midterm 1: Wednesday, February 22nd, 8:30pm. Location: Old Engineering 143. It covers sections 1 through 4 of chapter 8.
Midterm 2: Monday, March 19th, 8:30pm. Location: Old Engineering 143. It covers the remaining of chapter 8 until 8.7.
Final Exam: Monday, May 14th, location TBA. It covers chapters 7 and 8 and a section on Differential Equations.

Extra HW.
For the HW assignment, see the MAT127 webpage. Here are some extra exercises that you are encouraged to try. If you hand these in along with the HW, I may consider them as extra credit at the end of the semester. I.e., although no points will be a priori given to these problems, having done them may boost your grade if by the end of the course you are in a borderline case. Unless stated otherwise, problems are from the textbook. Bold numbers indicate the textbook section.

2.5: 23, 26, 28, 30, 32, 4.5: 11, 27, 28, 35, due on Wed 2/1.

8.2: 15, 25, , 29, 41, 53 due on Wed 2/8.

These problems, due on Wed 2/15.

These are problems from exams of previous years. All of them are due on Wed 2/22. Here the assignment: all problems of this exam; all problems of this exam; and problems 2, 3, 4 and 5 of this exam. If you have time, please try also problems 2,3 and 4 of this exam; problems 1, 2, 3 and 4 of this exam; problems 1, 2, 3 and 4 of this exam.

Redo all questions of the First Midterm. Due date Thu 3/8. You can get a blank copy of the exam here.

Redo all questions of the Second Midterm. Do problems 1, 7, and 14 of section 7.1. Due date Thu 3/29.

Review exercises of chapter 8 (page 628 of the textbook). Concept check: problems 1 to 12; True or false quiz: problems 1 o 20; Exercises: problems 1 to 22. Exercises of section 7.1, page 498: 1, 3, 9, 14, 15. Exercises of section 7.2, page 506: 1, 3, 9, 19, 27, 28. Due date: April 11th, 9:35am.

7.3: 2, 12, 16, 18, 21, 29, 30, 31, 44, 46, 48. Due on Thu, April 19th, in class.

Announcements and extra material.


Here you can find a list of common mistakes done by students in MAT127. Even though this seems very simple, make sure you understand the math involved in order to avoid such mistakes.

This is a copy of the Fall 2010 Early Exam, designed to check your knowledge of MAT125 and MAT126. If you have trouble with these problems, then you need to review the corresponding material as soon as possible. In doing so, don't forget to make the most of the MLC and my office hours.

There is a nice set of lecture notes by Gregory Naber, containing several examples, at:

The relevant chapters for our course are 50 to 59, but you may find other parts of those lecture notes useful to reivew Calc A and B material.

You may also find some useful material browsing the MAT 127 webpages from previous semesters. You can find several of them here.

And if you can only learn things by seeing tons of examples, you should have a look at the textbook "Schaum's outline of calculus" (or one of its variants), which contains more than 1000 problems solved. It can be found in the library or bought by a reasonable price on Amazon.

Sections 8.1 to 8.5 - First Miderm Material:

How come the harmonic series diverges? If you are having trouble understanding the divergence of the harmonic series, check this material.

Practice for the first midterm. On the main MAT127 webpage, exams from previous years have been posted along with their solutions. You should try those problems as a practice for the midterm. Also go over the HW problems, and remember their solutions have been posted as well (again, check the main MAT127 webpage). For problems reviewing more conceptual aspects of the material, click here. And here is a summary of convergence tests.

Extra Class - Review for the first midterm!
Sunday, February 19th, 4pm.
Location: room P-131 in the Mathematics Building.
Monday, February 20th, 7:30pm, again room P-131 of the Mathematics Building.
Remember that review session are based on student's questions, so review the material and bring your doubts.
