Trigonometric Functions
When applied to a series, all of the trigonometric functions operate on every observation in the current sample and return a value for every observation. Where relevant, the input and results should/will be expressed in radians. All results are real valued—complex values will return NAs.
arc cosine (real results in radians)
arc sine (real results in radians)
arc tangent (results in radians)
cosine (argument in radians)
sine (argument in radians)
tangent (argument in radians)
