Course Description
This is a one semester course for students who wish to prepare for MATH 1120 Calculus. It covers graphing and solution of equations involving polynomial, rational, circular, trigonometric, inverse trigonometric, logarithmic and exponential functions, in addition to conic sections. This is a challenging course that moves through the topics required for later study of calculus quickly and in depth. Students who have never taken Precalculus 12 or Principles of Math 12 are advised to take MATH 1105 first. A graphing calculator is required.
Course Content
1. General Functions
2. Polynomial and Rational Functions
3. Exponential and Logarithmic Functions
4. Trigonometric Functions
5. Analytic Trigonometry and Applications
6. Conics
7. Optional Topics
Learning Outcomes

Upon completion of MATH 1110 the student should be able to:

FUNCTIONS

• understand the concept of function and be able to determine which relations are functions by an examination of the equation and/or the graph of the relation.
• find the domain of any function and the range of functions for which the inverse can be determined or for which the graph can be easily sketched.
• extract the functional rule from a 'word problem'.
• determine if a function is odd or even and understand the graphical implication of the property.
• sketch the graphs of the following functions:

y = x, y = x2, y = x3, y = |x|, y = sqrt(x), y = 1/x, y = 1/x2, y = sqrt(a2 - x2)

• sketch the graphs of the following transformations of the above functions:

y = f(x) + c, y = f (x + c), y = -f(x), y = cf(x), y = f(cx)

Means of Assessment

Evaluation will be carried out in accordance with Douglas College policy. The instructor will present a written course outline with specific evaluation criteria at the beginning of the semester. Evaluation will be based on some of the following:

 Weekly Quizzes 0-40% Tests 20-70%* Assignments 0-15% Attendance 0-5% Class Participation 0-5% Final Examination 30-40%

* no single in-term exam to be worth more than the Final Examination

Note:  Students may be required to obtain a minimum grade or percentage on the Final Examination in order to be eligible to pass the course as indicated in individual instructor course outline.
