Student Outcomes

  • Students prove the Pythagorean identity sin2(x) + cos2(x) = 1.
  • Students extend trigonometric identities to the real line, with attention to domain and range.
  • Students use the Pythagorean identity to find sin(θ), cos(θ), or tan(θ), given sin(θ), cos(θ), or tan(θ) and the quadrant of the terminal ray of the rotation.
