Hours (Tent.):  MTWR 9:30-10:30      AND BY APPOINTMENT or by CHANCE! [available after class for appointments.]
  • 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: Edward Burger,Precalculus w/ Workbook (CD-ROM Set +Print Companion),Thinkwell,1-931381-94-1
    Register for Thinkwell on-line here.
  • On-Line Materials: Sensible PreCalculus (Text Notes plus) by M. Flashman
  • SCOPE: We will cover topics primarily related to theory and application of Functions: Polynomial, Rational, Exponential, Logarithmic, and Trigonometric. Supplementary materials will be provided as appropriate.
  • TESTS and ASSIGNMENTS:  Homework assignments are made regularly. We may use Blackboard or the Thinkwell website  to grade homework.
  • Homework results should be recorded by 9:00 pm of the due date to receive credit.
  • I will discuss this further at the first class meeting. Assignments will be discussed in class on a daily basis.
  • The reality check quizzes, some done outside class online ( Blackboard or Thinkwell) and some in-class tests, will have problems similar to assignments and class examples. There will be at least three in-class tests (15-30 minutes). 
  • The final examination for the course will be comprehensive.
    It will be given in two parts on the last two classes of the term.
    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
    Homework 200 points
    Final Examination 400 or 600 points
    Total 1300 or 1500  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.
    A grade of less than 50% on the final examination may result in a final grade of  F without offsetting high quality work on the other parts of the course.
  • 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 check  the summer session course list for a full list of relevant days.
  • Technology: A 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: 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 reality check quizzes, routine problems from homework after they have been discussed in class,   as well as using  technology.

    Regular use of my time outside of class 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
