Notes regarding cyclic equal values:
Sine – matching pairs are symmetrical within (0,
π
) and (
π
π
) centered around
π
2
. and
3
π
2
respectively. So the value of sine(
π
6
) is
the same as sin(
π
π

) and the value of sin(

) is the same as sin(

Cosine – matching pairs are symmetrical around
π
over the domain of [0, 2
π
]. So the value of cos(
π
6
) is the same as cos(
π
π
6
Tangent – matching pairs are
π
apart over the interval [0, 2
π
]. So the value of tan(
π
6
) is the same as tan(
