cf.DomainAncillary.sin

DomainAncillary.sin(i=False)

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

Units are accounted for in the calculation. For example, the the sine of 90 degrees_east is 1.0, as is the sine of 1.57079632 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

Examples:

>>> c.Units
<CF Units: degrees_north>
>>> print c.array
[[-90 0 90 --]]
>>> c.sin()
>>> c.Units
<CF Units: 1>
>>> print c.array
[[-1.0 0.0 1.0 --]]

>>> c.Units
<CF Units: m s-1>
>>> print c.array
[[1 2 3 --]]
>>> c.sin()
>>> c.Units
<CF Units: 1>
>>> print c.array
[[0.841470984808 0.909297426826 0.14112000806 --]]
