Send by email
Essential Questions: 
  • How can we name functions?
  • What are qualities of the trigonometric functions that other functions we have studied do not have?
  • How can we use sine, cosine, and tangent to solve real world problems?
Content: 
  • Sine, cosine, and tangent of a right triangle (SOHCAHTOA).
  • Values for sine, cosine, and tangent can be related to the similarity of right triangles with congruent angles.
  • Graphs of sine and cosine from 0 to 90 degrees.
  • Sine, cosine, and tangent of special angles.
  • Sine and cosine as parametric functions.
  • Inverse sine, inverse cosine, and inverse tangent problems.
  • Projectile motion problems (optional).
Skills and Processes: 
  • Solving for sides and angles of right triangles.
  • Using sine and cosine with parametric equations to solve wind and water problems.
  • Apply sine and cosine to application problems.
