High school · High School: Functions — Trigonometric Functions

(+) 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 π—x, π+x, and 2π—x in terms of their values for x, where x is any real number.
