suggest you make corrects to your previous exams.
- WebWork was down until mid-day 3/29 so here's what we'll do: everyone
gets full credit for SeriesHmwk2 and SeriesHwmk3 (I'll do this by
hand). But, do all these problems, without looking at solutions first, and bring questions for review in class on Thursday 3/30.
- Exam II is Tuesday 4/4 in class.
- Due 3/28 and 3/30. I broke the assignment into two shorter ones, WebWork
SeriesHmwk2 and SeriesHmwk3. Do both. We've covered enough material for you to do both
now, but I gave them serparate due dates so we can cover some in the next
class (if you ask).
- Due 3/23. Read 8.4.

hand in: Ch 5.8 # 3,
11, 28, 33, 41, 42. Read 45 and try it if you find it interesting. The other
application problems in this section are nice as well!

Previous Final Exams in 143.
This course is the third part of a three semester sequence in calculus (Math
141, 142, and 143), which focuses on techniques of integration and infinite
series. We'll cover in order Chapters 6 and 8 of Essential Calculus, by
Stewart, along with seciton 5.8 (between 6.5 and 6.6).
This course satisfies the Mathematical and Quantitative Reasoning (MQR)
requirement of the Pathways General Education Required Core. See here for a
description of the MQR Learning Outcomes.
It is a pre-requisite that you have taken MATH 132 or 142. MATH 151 does not
satisfy the prerequisite.
Here is some futher basic information:
- Location: Tuesday, Thursday 12:15-1:30. Kiely 273.
- Textbook: "Essential Calculus" Second Edition, by James Stewart.
- Instructor: Scott Wilson

The homework will be completed online through
You must have an active CAMS account to use WebWork. To create an account, go
to the Help Desk. To login to WebWork, enter your CAMS username IN ALL LOWER
CASE (e.g. alastname100 for Alicia Lastname). Enter your CAMS password (not
your CUNY Portal account password).
I will post homework assignments to be completed following each lecture. The
due dates are indicated with the assignment, but they will generally be due on
Sundays and Thursdays at noon. No extensions will be granted, but I
will drop the two lowest homework grades.
Getting Help- MathLab
The Math Lab will be open (in-person) Monday-Thursday, from 9am-5pm, starting
Monday, January 30th. They will offer limited online/remote services on
Friday, weekends, and evenings, starting Friday, January 27th. Click the
link for details.
You are encouraged to use graphing calculators in this course (e.g. TI-84). There will be
homework problems and test questions which require their use. Instructions on
the use of the TI-84 will be given during lecture, and I suggest you bring your calculator to
class. You are not permitted to use calculators
that can perform symbolic differentiation or integration (e.g. TI-89 or TI-92).
The final grade will be based on the homework (25%), three in-class exams (50%
total), and the final exam (25%). The preliminary exams are in-class and will
