Mathematics Curriculum
  Trigonometry
 

Trigonometry topics include circular functions, right triangle ratios, solutions of trigonometric equations, inverses, identities, the laws of sines and cosines, graphs of trigonometric functions, and applications of trigonometric techniques to solve real-world problems. A transformational approach to graphing is used with families of related graphs. Numerical, graphical, and algebraic solutions should be considered for all problems where appropriate. Graphing utilities, especially graphing calculators, are integral to the course.
