method

classmethod polynomial.legendre.Legendre.identity(domain=None, window=None, symbol='x')[source]#

Identity function.

If p is the returned series, then p(x) == x for all values of x.

Parameters:
domain{None, array_like}, optional

If given, the array must be of the form [beg, end], where beg and end are the endpoints of the domain. If None is given then the class domain is used. The default is None.

window{None, array_like}, optional

If given, the resulting array must be if the form [beg, end], where beg and end are the endpoints of the window. If None is given then the class window is used. The default is None.

symbolstr, optional

Symbol representing the independent variable. Default is ‘x’.

Returns:
new_seriesseries

Series of representing the identity.
