Math 19000: College Algebra and Trigonometry
Supervisor: Matthew Auth
Introduction to algebraic expressions and equations, rational expressions, exponents, functions and their graphs, trigonometric functions on the unit circle, and right triangle trig. Prereq.: placement at college entry or by subsequent examination. 4 hr./wk.; 3 credits.
Individual section instructors may alter the schedule slightly due to holidays, or in order to spend more (or less) time on a given topic.
Lesson Summaries with Video Links for Flipped Classroom
The videos are grouped by textbook section. It can be helpful to watch the videos for the day's lesson before coming to class. You can even try some of the optional linked Khan Academy exercises. You will get more out of class by first watching a couple videos beforehand. After watching the videos you will then have more time to work on problems during class. Doing problems is most important. It is impossible to learn math by only watching videos. You must pause each math video frequently to work out the given problem for yourself on scrap paper.
The summaries can be helpful to consult for a quick overview of each section covered in the syllabus. While reading you will learn what concepts and techniques are most important in each section, and what topics can be skipped or deemphasized. Ultimately, working through the assigned webassign hw problems on your own or in groups of students is most important. The only way to learn the material in this course is to do many problems on your own.
We will use webassign or gradescope or the instructor to grade homework and in-class quizzes in this class. Webassign quizzes can only be taken in-person during class. There are no make-up quizzes. You may take the quizzes with your phone or with a laptop. If you plan to use your phone, please practice beforehand. Some students complain that they have difficulties entering webassign answers on their phones. One solution is to change your phone web browser. If that does not work, you may borrow an iPad or laptop from the ccny iMedia office on the first floor of the NAC building. You will get two attempts for each webassign quiz question.
Here is the best advice: Consistently do lots of problems. Between WebAssign, textbook examples and exercises, and Khan Academy practice sets linked above, there are more problems than any one student (or instructor) can complete. The webassign hw sets are most important. All exam questions will be chosen similar to the problems on your assigned webassign hw sets and webassign quizzes. It is better to consistently to spend two hours every day doing an assortment of math problems than to spend the weekend before an exam cramming. Consider the final exam like running a marathon and the problems as your training sessions. Ultimately this is a tesIf you consistently do problems (train) then you will be well-prepared for the final exam but if you take long gaps between working on problems you will always have difficulty getting back into the math mindset necessary to complete the problems. The first day of training is always the most painful.
Do your assigned webassign problems consistently throughout the week. Since our major exams will be written (and without electronics) work out each webassign problem step by step with scrap paper before typing your final answer on the computer.
After the assignment due date you will see the answer to each question. You can (and should) use the "Ask Another Version" button on past due hw assignments to continue to practice different versions of the hw questions.
Finally use the "Ask Your Teacher" button to ask questions while doing a webassign assignment. Each problem on your webassign assignments will have an "Ask Your Teacher" button. By clicking the button and describing what you are thinking on a given problem is a great way to get help. It also helps your instructor to know what topics must be reviewed.
Workbook Problems using Scrap Paper Only. NO technology.
Webassign is great to practice solving problems, but it is essential that you work each problem with scrap paper by your side. You cannot learn math by typing guessed answers into webassign on your phone. There will be no technology used on exams. You must work out all exam problems with scrap paper only. Practice your hw problems using scrap paper only. You will be better prepared for the exams that way. In order to force you to do work on scrap paper there will be some written quizzes and classwork assignments.
We will provide a class exercise book to encourage you to continuously write solutions to math problems.
Read the Book
Here is some good advice: Read the textbook. Learning how to read a math textbook will be helpful in all your future math courses. Start practicing reading your math textbook now. You get a free e-copy of our textbook with your webassign access key. There are good videos, formula lists, and worked examples in each section of our book. You can find topics, advice reading textbook, examples in the section to know, examples in the section to avoid, end of section exercises to try (odd answers in back), as well as relevant Khan Academy videos, practice problem sets, and overviews in the course topics link above.
Working alone on your math exercises sets and getting stuck is frustrating, but it is a best way to learn math. Really focusing and trying to sort out your ideas while stuck on a problem is an essential way to learn a math concept. Do not panic. We all sometimes get stuck on a problem. However do not remain stuck for too long, for more than a couple days. There are many ways to get help. Experiment with different ways to get support and find a method that works for you. Do your assigned webassign problems consistently throughout the week. Since our major exams will be written (and without electronics) work out each webassign problem with scrap paper before typing your final answer on the computer.

Webassign HW: 5% of course grade.
In-Class Quizzes / Classwork: 10% of course grade.
Midterm Exam 1: 15% of course grade.
Midterm Exam 2: 15% of course grade.
Midterm Exam 3: 15% of course grade.
Final exam 40% of course grade
However at then end of the course if your final exam average is superior to any of your midterm grades, then you can use your final exam grade to replace all lower midterm average(s). For instance if your midterm 1 grade 70, your midterm 2 grade 87, your midterm 3 grade was 79 and your final exam grade 75 then your grade will be computed as
5% * (hw grade) + 10% * (quiz average) + 15% * 87 + + 15% * 79 + 55% * 75 = course grade.
You can even replace both midterm exam scores if your final is superior to both. One way to think of these grading factors is that your performance on midterms cannot hurt your final grade, as compared to your final exam grade. Your performance on the midterms can only help your grade in comparison to your final exam score. If you miss a midterm exam for any reason, your final exam grade will be used to make-up your missed midterm.
Your quiz or hw average CANNOT be replaced by your final exam grade. There will be many quizzes, at least once a week--maybe more. There will be no make-up quizzes. Instead your lowest three quiz grades will be dropped before computing your quiz average.
With these grading factors you will be less stressed taking the midterms knowing that you can replace a bad score with your final exam score. Moreover, if you feel ill, test positive for covid, you can skip either midterm, or both midterms. However, you must take the final. If you are sick for the final, do not come to campus. There will be a make-up final exam.
Sample Midterm and Final Exams
NO ELECTRONICS OR CALCULATORS ON MIDTERM AND FINAL EXAMS. Midterm and final exams will be given in-person. All sample exam questions modeled on the assigned webassign homework problems. If you've worked through the assigned webassign homework and classwork problems there should be no surprises on the written exams. Your grade in this course depends on your performance on the written midterm and final exams. It is you against the questions on the webassign questions on these tests. The best way to prepare to take these written exams is by continuously practicing webassign hw, classwork, and quiz questions. The sample exams below have been included to give you an idea of the exam format. During any semester exam problems will be shuffled between the assigned webassign problems from those sections, however the exam format will be similar to the format of the exams below.
Sample Exam 1. Two questions from each secion, P2-P7.
Sample Exam 1A. Two questions from each section, P2-P7.
Sample Exam 2. Questions from P8--1.8 on our syllabus.
Sample Exam 2A. Questions from P8--1.8 on our syllabus.
Sample Exam 3. Questions from 2.1-3.1 inclusive on our syllabus.
Sample Exam 3A. Questions from 2.1-3.1 inclusive on our syllabus.
Sample Final Exam. Questions from the final exam are picked from all sections on our syllabus.
Sample Final Exam 2. Questions from the final exam are picked from all sections on our syllabus.
Discounted Webassign Access Code ($44)
If you have not already purchased a 190 Webassign Access code, you can purchase one for $44 by following each step until you reach step 5A in the Strong Start Student Guide. If you already purchased a 190 Webassign Access code in a previous semester, do NOT purchase another code. Your old code will work this semester. The access code remains valid even if you need to take math 190 multiple times. Before you purchase an access code, you should take advantage of the free trial before purchasing in case you need to drop the course.
(If you are taking multiple courses outside the math dept. that also require a webassign access code, then Cengage Unlimited may save you money? You should then compute what is the best value for your semester. If this is the only class with Webassign you are taking this semester, the cheapest option (step 5A) to purchase an access code that I know is the $44 option in the above link.)
