Sean Owen commented on SPARK-23329:
-----------------------------------
Sure, though I might simplify that a bit.
{code}
/**
* @param e angle in radians
* @return sine of the angle, as if computed by [[java.lang.Math.sin]]
* ...
*/
{code}
Perhaps this can be limited to improving the documentation of all trigonometric
functions.

> Labels: starter

> We need an update on the function descriptions for all the trigonometric
> functions. For example, {{cos}}, {{sin}}, and {{cot}}. Internally, the
> implementation is based on the java.lang.Math. We need a clear description
> about the units of the input arguments and the returned values.
> For example, the following descriptions are lacking such info.
