# numpy.polynomial.chebyshev.Chebyshev.basis

classmethod `Chebyshev.``basis`(deg, domain=None, window=None)

  Series basis polynomial of degree deg.

  Returns the series representing the basis polynomial of degree deg.

  New in version 1.7.0.

  Parameters: | deg : int Degree of the basis polynomial for the series. Must be >= 0. 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.
  Returns: | new_series : series A series with the coefficient of the deg term set to one and all others zero.
