Khan Academy: Trigonometry Course Overview

This course provides a comprehensive study of trigonometry, organized into four primary units covering right triangles, functions, non-right triangles, and equations/identities.

• Unit 1: Right Triangles & Trigonometry
  • Focuses on ratios (sine, cosine, tangent), reciprocal ratios, and solving for unknown sides and angles.
  • Includes applications such as right triangle word problems and the relationship between complementary angles.
• Unit 2: Trigonometric Functions
  • Covers the unit circle, radians vs. degrees, and the Pythagorean identity.
  • Explores the properties of sinusoidal functions, including amplitude, midline, period, and phase shifts.
  • Includes graphing techniques and modeling real-world scenarios (e.g., temperature, length of day).
• Unit 3: Non-Right Triangles & Trigonometry
  • Covers the Law of Sines and the Law of Cosines for solving oblique triangles.
• Unit 4: Trigonometric Equations and Identities
  • Focuses on inverse trigonometric functions and solving sinusoidal equations.
  • Covers angle addition identities and their application in finding trig values, side lengths, and manipulating expressions.
• Assessment Structure: Each unit includes multiple quizzes and a final unit test to evaluate student mastery.
