Course-level Learning Objectives (CLOs)
Upon successful completion of this course, students will be able to:

  1. Solve problems involving an understanding of the concept of a function and the related concepts of domain, range, composition of functions and inverse functions; and demonstrate understanding of these concepts using functions given in graphical, symbolic, or numerical form.
  2. Correctly use mathematical notation and language related to the above concepts.
  3. Graph a variety of functions and be able to interpret their graphs.
  4. Formulate and apply properties, graphs and some appropriate applications of linear, polynomial, rational, exponential, logarithmic, trigonometric, and inverse trigonometric functions.
  5. Solve equations and inequalities involving the aforementioned functions, both graphically and algebraically.
  6. Demonstrate how and when to use technology as a tool in solving equations and investigating the behavior of functions and graphs.
  7. Construct equations and functions involving the aforementioned functions that model situations described in words.
  8. Use the above abilities to solve word problems and to express solutions clearly.
  9. Solve problems involving right triangle trigonometry, the law of sines and the law of cosines.
