- define a function
- determine domains and ranges of functions and represent them using interval notation
- use the vertical line test to determine whether a relation is a function
- classify functions as periodic, one-to-one, piecewise, or continuous
- identify maxima, minima, and intervals of increase/decrease from the graph of a function
- apply transformations (translations, dilations and reflections) to functions
- find a formula for the inverse of a function and graph the inverse function
- evaluate composite functions
- use linear functions that model real-life situations to solve problems
- find the vertex of a parabola by completing the square
- use quadratic functions that model real-life situations to solve problems including optimization problems
- solve quadratic inequalities both analytically and graphically, and express the solutions in interval notation
- graph polynomial functions
- apply the Remainder Theorem and Factor Theorem when dividing polynomials
- divide polynomials using long division and synthetic division
- solve factorable polynomial equations
- graph exponential and logarithmic functions with any base and be able to identify axis-intercepts, asymptotes, domain and range
- exploit the inverse relationship between exponential and logarithmic functions to solve problems
- convert between logarithmic and exponential forms
- evaluate simple logarithms without using a calculator
- change logarithms from one base to another
- use the properties of logarithms to simplify expressions
- solve logarithmic and exponential equations with any base
- define sine, cosine, tangent, secant, cosecant and cotangent in terms of: right triangles, points-in-the-plane and unit circles
- use a calculator to find the trigonometric values for any acute angle, and given the function value for an acute angle, find the angle
- solve right triangles, and word problems involving right triangles, using trigonometry
- convert from degree measure to radian measure and vice versa
- identify special angles on a unit circle
- use reciprocal and Pythagorean identities to simplify trigonometric expressions
- solve simple trigonometric equations giving only the acute angle solution
- graph the sine and cosine functions
- from the graph of a trigonometric function determine the period, amplitude, domain, range and phase shift
- solve systems of equations in two variables using substitution or elimination methods
- solve systems of equations in three variables using the substitution method
- distinguish between sequences and series (geometric and arithmetic)
- write formulas for arithmetic and geometric sequences both explicitly and recursively
- use formulas to find terms, and the positions of terms, in sequences or series; arithmetic or geometric means; sums of series
- use sigma notation to describe series
- evaluate series described in sigma notation
Evaluation will be carried out in accordance with the Douglas College Evaluation Policy. The instructor will present a written course outline with specific evaluation criteria at the beginning of the semester. Evaluation will be based on the following:
Quizzes | 0 - 40% |
Term tests | 20 - 70% |
Assignments | 0 - 15% |
Attendance | 0 - 5% |
Class Participation | 0 - 5% |
Final examination | 30 - 40% |
Note: All sections of a course with a common final examination will have the same weight given to that examination.
