DomainAncillary.tan(i=False)

Take the trigonometric tangent of the data array and bounds in place.

Units are accounted for in the calculation, so that the the tangent of 180 degrees_east is 0.0, as is the sine of 3.141592653589793 radians. If the units are not equivalent to radians (such as Kelvin) then they are treated as if they were radians.

The Units are changed to ‘1’ (nondimensionsal).

New in version 2.0.

Parameters:

i: bool, optional

If True then update the domain ancillary in place. By default a new domain ancillary is created. In either case, a domain ancillary is returned.

Returns:

out : cf.DomainAncillary
