Special Right Triangles

Determining the values of sine, cosine, & tangent, using special right triangles and applying their properties to real-world phenomena.

Mapped to CCSS Section# HSF.TF.A.3

Use special triangles to determine geometrically the values of sine, cosine, tangent for π/3, π/4 and π/6, and use the unit circle to express the values of sine, cosine, and tangent for x, π + x, and 2π – x in terms of their values for x, where x is any real number.
