Scope & Sequence Trigonometry  

Give students a head start on college math! Made for those who've completed Algebra II, SOS Trigonometry for grades 9-12 prepares high schoolers for future advanced math courses. Offering a five-unit study with a review, this high school elective helps teach students how to develop trigonometric formulas and use them in real world applications. Topics include:

  • right angle trigonometry
  • graphing
  • trigonometric identities
  • the laws of sines and cosines
  • polar coordinates

Helping students see the big picture of mathematics, SOS Trigonometry shows the use of trigonometry as a tool for indirect measurement, explains the natural phenomenon of trigonometric functions, and gives an understanding of how algebraic and geometric concepts work together. SOS Trigonometry is a great alternative to students not pursuing calculus!
