%feature("docstring") OT::ArcsineMuSigma
"Arcsine distribution parameters.

Available constructors:
    ArcsineMuSigma(*mu=1.0, sigma=1.0*)

Parameters
----------
mu : float
    Mean.
sigma : float
    Standard deviation :math:`\\\\sigma > 0`.

Notes
-----
The native parameters are defined as follows:

.. math::

    a &= \\\\mu - \\\\sigma \\\\sqrt{2} \\\\\\\\
    b &= \\\\mu + \\\\sigma \\\\sqrt{2}

Arcsine

Examples
--------
Create the parameters of the Arcsine distribution:

>>> import openturns as ot
>>> parameters = ot.ArcsineMuSigma(8.4, 2.25)

Convert parameters into the native parameters:

>>> print(parameters([8.4, 2.25]))
[5.21802,11.582]

The gradient of the transformation of the native parameters into the new
parameters:

>>> print(parameters.gradient())
[[  1        1       ]
 [ -1.41421  1.41421 ]]"
