cf.Count.sin

Count.sin(inplace=False, i=False)[source]

The trigonometric sine of the data, element-wise.

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).

The “standard_name” and “long_name” properties are removed from the result.

Parameters:
inplace: bool, optional

If True then do the operation in-place and return None.

i: deprecated at version 3.0.0

Use inplace parameter instead.
Returns:

The construct with the sine of data values. If the operation was in-place then None is returned.

Examples:

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

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