TEXTBOOK:     Precalculus, 2007 7/e by Larson & Hostetler (Houghton Mifflin Co.)

 

COURSE DESCRIPTION:

This course provides an intense study of the topics which are fundamental to the study of calculus. Emphasis is placed on functions and their graphs with special attention to polynomial, rational, exponential, logarithmic and trigonometric functions, and analytic trigonometry. Upon completion, students should be able to solve practical problems and use appropriate models for analysis and prediction. This course has been approved to satisfy the Comprehensive Articulation Agreement general education core requirement in natural sciences/mathematics.

  Two                Polynomial and Rational Functions

  Three             Exponential and Logarithmic Functions

  Four               Trigonometry

  Five               Analytic Trigonometry

  Six                  Additional Topics in Trigonometry

 

COURSE COMPETENCIES:

For satisfactory completion of Precalculus, the students must demonstrate by written examination that they can do the following.  (Order of competence does not imply the order of presentation.)

 

1)             Perform arithmetic operations with polynomials and algebraic fractions.

2)             Simplify complex fractions.

3)             Simplify and evaluate powers having rational exponents.

4)             Simplify Radicals.

5)             Factor Polynomials.

6)             Perform arithmetic operations with complex numbers.

7)             Solve linear and quadratic equations.

8)             Solve equations linear or quadratic in form.

9)             Solve word problems which can be modeled by a linear or quadratic equation.

10)         Solve inequalities.

11)         Solve equations and inequalities involving absolute value expressions.

12)         Determine whether a given relation is a function.

13)         Find the domain and range of a function.

14)         Graph algebraic and absolute value functions on the Cartesian Coordinate System.

15)         Use symmetry and translation to sketch the graphs of given functions.

16)         Given functions f and g, find f + g, f - g, f . g, f/g, f -1, and fog.

17)         Graph exponential and logarithmic functions.

18)         Evaluate logb(x) for allowable values of b and x.

19)         Use properties of logarithms to simplify or expand logarithmic expressions.

20)         Solve exponential and logarithmic equations.

21)         Solve word problems which can be modeled by an exponential or logarithmic function.

22)         Solve a system of two equations in two unknowns.

23)         Solve word problems which can be modeled by a system of equations.

24)         Convert degrees to radians and convert radians to degrees.

25)         Convert decimal degrees to degrees, minutes, and seconds and vice versa.

26)         Evaluate trig functions for angles given in degrees or radians

27)         Graph trig functions of the form y = a fcn(bx+c) + d and explain how the constants a, b, c, and d affect the graph.

28)         Determine and graph the inverse of given trig functions and give the domain and range of the inverse function.

29)         Use the trig functions and the Pythagorean Theorem to solve right triangles.

30)         State the basic trigonometric identities and use those identities to verify other identities.

31)         Solve trigonometric equations.

32)         Use the law of sines and the law of consines to solve any triangle.

33)         Express complex numbers in trigonometric form and convert from trigonometric form to rectangular form.

34)         Multiply and divide complex numbers in trig form and use Demoivre’s Theorem to raise to powers and take roots of complex numbers.

 

 

COURSE AVERAGE:                           10% homework and/or pop quiz average

75% major test average

15% comprehensive final examination.

 

A student who has two or fewer absences may drop the lowest of the pop quiz grades in determining the pop quiz average.  A student who has more than two absences, may not drop any pop quiz grade. No distinction is made between excused and unexcused absences. (Being tardy is an unexcused absence.)
