cf.Count.cos¶

Count.
cos
(*args, **kwargs)[source]¶ Take the trigonometric cosine of the data elementwise.
Units are accounted for in the calculation, so that the cosine of 90 degrees_east is 0.0, as is the cosine 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 output units are ‘1’ (nondimensional).
The “standard_name” and “long_name” properties are removed from the result.

Examples
>>> f.Units <Units: degrees_east> >>> print(f.array) [[90 0 90 ]] >>> g = f.cos() >>> g.Units <Units: 1> >>> print(g.array) [[0.0 1.0 0.0 ]]
>>> f.Units <Units: m s1> >>> print(f.array) [[1 2 3 ]] >>> f.cos(inplace=True) >>> f.Units <Units: 1> >>> print(f.array) [[0.540302305868 0.416146836547 0.9899924966 ]]
