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’.
