Learning Outcomes

Upon successful completion of the course, students will be able to:

  • Graph functions and relations in rectangular coordinates and polar coordinates;
  • Synthesize results from the graphs and/or equations of functions and relations;
  • Apply transformations to the graphs of functions and relations;
  • Recognize the relationship between functions and their inverses graphically and algebraically;
  • Solve and apply equations including rational, linear, polynomial, exponential, absolute value, radical, and logarithmic, and solve linear, nonlinear, and absolute value inequalities;
  • Solve systems of equations and inequalities;
  • Apply functions to model real world applications;
  • Identify special triangles and their related angle and side measures;
  • Evaluate the trigonometric function of an angle given in degree and radian measure;
  • Manipulate and simplify a trigonometric expression;
  • Solve trigonometric equations, triangles, and applications;
  • Graph the basic trigonometric functions and apply changes in period, phase and amplitude to generate new graphs; and
  • Prove trigonometric identities


Tests, examinations, homework or projects where students demonstrate their mastery of the learning objectives and their ability to devise, organize and present complete solutions to problems.
