Often, the hypotenuse is unknown and would need to be calculated before using arcsine or arccosine using the Pythagorean Theorem: a 2 + b 2 = h 2 \displaystyle a^2+b^2=h^2 where h \displaystyle h is the length of the hypotenuse. Arctangent comes in handy in this situation, as the length of the hypotenuse is not needed.

As an instance of the rv_continuous class, arcsine object inherits from ita collection of generic methods (see below for the full list),and completes them with details specific for this particular distribution.
