Trigonometry

Key ideas

• • The unit circle (sin x, cos x, tan x)

  • Conversions between degrees and radians

  • Special triangles

  • Reciprocal trigonometric functions

  • Solving trigonometric functions (sine, cosine and tangent) that are:

    • Simple

    • Translated 

    • General solutions

  • Modelling with trigonometric functions in the form:

    • y = A sin B(x - C) + D

    • y = A cos B(x - C) + D

  • Trigonometric identities, with less emphasis on proof
