Undergraduate Courses

MA 113, Precalculus Trigonometry

Course Objectives

MA 113 has two main objectives.

  • To help prepare students for calculus. MA 113 is the second course in a two-course precaclulus sequence; the first course is MA 112, Precaclulus Algebra.
  • To stand alone, as a self-contained course in college trigonometry

More specifically, a student who successfully completes MA 113 should

  • understand and be able to use degree and radian measures of angles and be able to convert between them.
  • know and be able to use the basic properties and identities of the trigonometric functions
  • understand polar coordinates and be able to convert between rectangular and polar coordinates
  • understand how inverses of trigonometric functions can be formed by restricting the domains of these functions.
  • know and be able to use the basic properties of the inverse sine and tangent functions.
  • be able to solve simple equations involving trigonometric and inverse trigonometric functions
  • recognize common trigonometric fallacies, particularly those that involve the improper interchange of operations.
  • be able to translate simple applied problems into the language of mathematics, and have a general understanding of the applications of the trigonometric functions.
  • understand complex numbers and their operations and the connection with trigonometric functions
  • make progress towards the general goal of being able to learn, use, and communicate mathematics independently
