    Hours (Tent.): MTF 3:20-4:40      AND BY APPOINTMENT or by CHANCE!
  • PREREQUISITE: Math code 40 (or better) or permission.
  • Catalog Description: Functions and their graphs; in-depth treatment of exponential and logarithmic functions. Trigonometry: trigonometric functions, identities, solving triangles. Polynomial functions. Prerequisite: HSU MATH 42 or 44 or 45 or math code 40.
  • TEXT: Sullivan and Sullivan, Precalculus Enhanced with Graphing Utilities, third edition, Prentice-Hall, 2002.

    • [The ISBN for the HSU custom order text is 0536684812.]
  • SCOPE: We will cover topics primarily from the preliminaries and chapters 1-6 in S&S. Supplementary materials will be provided as appropriate.
  • TESTS and ASSIGNMENTS:  Homework assignments are made regularly. These assignments will be discussed in class on a daily basis.
  • The reality check quizzes (done outside class on Blackboard) and in-class tests will have similar problems. There will be three in-class tests (15-30 minutes). 

    • The final examination for the course will be comprehensive and will be self-scheduled during the final exam week.
    MAKE-UP TESTS WILL NOT BE GIVEN EXCEPT FOR VERY SPECIAL CIRCUMSTANCES!
    It is the student's responsibility to request a makeup promptly,
    especially for  especially for unauthorized absence.
    *** DAILY ATTENDANCE SHOULD BE A HABIT***
  • GRADES: Final grades will be determined taking into consideration the quality of work done in the course as evidenced primarily from the accumulation of points from tests and various  assignments.
    • Reality Quizzes 1-7 Best 6 scores 600 points
    Reality Quiz 8 100 points
    Cooperative work 50 points
    Homework 50 points
    Final Examination 400 or 600 points
    Total 1200 or 1400  points
  • Cooperative problem assignments will be used to determine 50 points.
  • The final examination will be be worth either 400 or 600 points determined by the following rule:

    • The final grade will use the score that maximizes the average for the term based on all possible points .
  • Notice that only 400 or 600 of these points are from formal in-class examinations, so regular participation is essential to forming a good foundation for your grades as well as your learning.
  • MORE THAN 4 ABSENCES MAY LOWER THE FINAL GRADE FOR POOR ATTENDANCE.

    • ** Students wishing to be graded with either CR or NC should make this request to the Adm & Rec office in writing. See the fall course list for a full list of relevant days.
  • Technology: The computer or a graphing calculator can be used for many problems. We will use Winplot and Microsoft Xcel.
  • Graphing Calculators: Graphing calculators are welcome and highly recommended.
  • Use of  Office Hours and Math 99: Many students find  pre-calculus difficult because of weakness in their algebra background skills and concepts.  A grade of C in Math 44 might indicate this kind of weakness.

    • Difficulties that might have been ignored or passed over in previous courses can be a major reason for why things don't make sense now.

    You may use my office hours for some additional work on these background areas either as individuals or in small groups. My office time is  also available to discuss routine problems from homework after they have been discussed in class,  reality check quizzes, as well as using  technology. Representatives from groups with questions about the Problem of the Week are also welcome.

    You may consider registering for Math 99(sections 5 or 6 - 42097 or 42527) Tutoring for Math 115. This is a 2 unit, credit/no credit "course" that provides generous tutorial assistance paid for by your registration. If you can afford the units, this is a good way to get help on specific problems.
    Regular use of my time outside of class or Math 99 should be especially useful for students having difficulty with the work and wishing to improve through a steady approach to mastering skills and concepts.

  • Don't be shy about asking for an appointment outside of the scheduled office hours
