cudf.Series.asin#

Series.asin()#

Get Trigonometric inverse sine, element-wise.

The inverse of sine so that, if y = x.sin(), then x = y.asin()

Returns
DataFrame/Series/Index

Result of the trigonometric operation.

Examples

>>> import cudf
>>> ser = cudf.Series([-1, 0, 1, 0.32434, 0.5])
>>> ser.asin()
0   -1.570796
1    0.000000
2    1.570796
3    0.330314
4    0.523599
dtype: float64

asin operation on DataFrame:

>>> df = cudf.DataFrame({'first': [-1, 0, 0.5],
...                      'second': [0.234, 0.3, 0.1]})
>>> df
   first  second
0   -1.0   0.234
1    0.0   0.300
2    0.5   0.100
>>> df.asin()
      first    second
0 -1.570796  0.236190
1  0.000000  0.304693
2  0.523599  0.100167

asin operation on Index:

>>> index = cudf.Index([-1, 0.4, 1, 0.3])
>>> index
Float64Index([-1.0, 0.4, 1.0, 0.3], dtype='float64')
>>> index.asin()
Float64Index([-1.5707963267948966, 0.41151684606748806,
            1.5707963267948966, 0.3046926540153975],
            dtype='float64')
