• Trigonometry

  • Defines ratios in right triangles: sine (sin), cosine (cos), and tangent (tan).
  • Utilizes the unit circle to analyze angles and their trigonometric values.
  • Involves identities (e.g., sin²θ + cos²θ = 1) and equations for solving problems related to angles.

• Calculus

  • Differentiation focuses on limits and the process of finding derivatives, which measure rates of change.
