MATH& 142 - Precalculus II

5.0 Credits
Continuation of MATH& 141. Covers trigonometric and inverse trigonometric functions, conic sections, parametric equations, polar coordinates and vectors. Includes applications. Graphing calculator required. Prerequisite
MATH& 141 or equivalent with a minimum grade of 2.0. Corequisite

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

  1. Evaluate trigonometric functions at values given in radians or degrees, using both right-angle and unit-circle approaches.
  2. Identify and communicate important features of trigonometric and inverse trigonometric functions (including domains, ranges, symmetry, periods and graphs) and important graphical features of conic sections.  
  3. Solve trigonometric equations using trigonometric identities, inverse trigonometric functions, algebra and technology.  
  4. Prove trigonometric identities.
  5. Translate between graphical and algebraic representations, between the Cartesian and parametric representations of equations and graphs, and between polar and rectangular coordinates.
  6. Recognize and sketch graphs of equations given in polar coordinates.
  7. Perform vector operations, including vector algebra and dot product.
  8. Use parametric representation, trigonometric functions, right-triangle trigonometry, the Law of Sines, the Law of Cosines, and vectors to model situations given in words and to solve applied problems.  
  9. Express solutions clearly with correct use of mathematical notation and terminology.
