CATALOG DESCRIPTION: PRECALCULUS II (3 semester hours) contains circular functions, trigonometric identities and equations, conic sections, complex numbers, and discrete algebra. Duplicate credits cannot be earned in any two of Math 127/128. The topical outline of course objectives is the following:

Chapter 5 5.1-5.4 Trigonometric functions: unit circle approach
Chapter 6 6.1-6.6 Trigonometric functions: right triangle approach
Chapter 7 7.1-7.5 Analytic trigonometry
Chapter 8 8.1-8.4 Polar coordinates and parametric equations
Chapter 11 11.1-11.4 Conic sections

PREREQUISITE: Three years of high school mathematics at the level of algebra and above and a satisfactory score on the Math Placement Test, or a minimum score of 25 on the ACT, or a minimum score of 560 on the SAT, or a C and above in Math 126 or equivalent.

TEST AND GRADING POLICY: There will be FOUR (100 minutes) tests evenly distributed within the summer term, each noncumulative test is worth 25%, covering sections that are learned recently. Grades will be assigned on the basis of total 100 points, distributed as follows:

Four tests 25% each
Total 100%

Final course letter grades will be assigned as follows:

A 95-100
A- 90-94
B+ 86-89
B 80-85
C+ 76-79
C 70-75
D 60-69
F 0-59

NOTE: Your grade will be EXCLUSIVELY based on the tests.

CLASS POLICIES:

ATTENDANCE:

You are expected to attend class regularly. If you miss a class for any reason, you are responsible for all materials covered, announcements made, and for acquiring materials that Jul have been distributed in class during your absence.

 

HOMEWORK:

The homework problems that you should work after each lecture are on the assignment list. You are required to do the homework outside of class for each section after we have completed the lesson, although they won't be collected/checked during the summer term.

 

TESTS:

Test problems will mostly be taken from the homework, or inspired by the homework. Make-up exam is not allowed due to the tight summer schedule. Failure to take an exam during the scheduled class time will result in a score of zero for that exam. Calculator is unallowed and also unnecessary in any test.

 

SURVIVAL GUIDE:

(1) Attend every class; (2) Solve all homework problems and practice problems; (3) Ask for help from the instructor during the office hours; (4) Take advantage of free math tutoring clinic offered by UNLV, possibly.

 

TUTORING & COACHING:

(1) UNLV Math Tutoring Clinic is located at CDC 701. Call 895-0366 or visit http://www.unlv.edu/math/math clinic.html for more information.

 

(2) The Academic Success Center (ASC) provides tutoring, academic success coaching, and other academic assistance for all UNLV undergraduate students. For information regarding tutoring subjects, tutoring times, and other ASC programs and services, please visit the ASC website, https://www.unlv.edu/asc, or call 702-895-3177. The ASC building is located across from the Student Services Complex (SSC). Academic success coaching is located on the second floor of SSC A, Room 254. Drop-in tutoring is located on the second floor of the Lied Library, and on the second floor of the College of Engineering building (TBE A 207). 

ACADEMIC INTEGRITY:

Academic integrity is the pursuit of scholarly activity in an open, honest and responsible manner. Academic integrity is a basic guiding principle for all academic activity at University of Nevada, Las Vegas, and all members of the University community are expected to act in accordance with this principle. Consistent with this expectation, the University's Code of Conduct states that all students should act with personal integrity, respect other students' dignity, rights and property, and help create and maintain an environment in which all can succeed through the fruits of their efforts.

Academic integrity includes a commitment not to engage in or tolerate acts of falsification, misrepresentation or deception. Such acts of dishonesty violate the fundamental ethical principles of the University community and compromise the worth of work completed by others. Based on the University's Student Academic Misconduct Policy, a range of academic sanctions Jul be taken against a student who engages in academic dishonesty.
