# numpy.polynomial.chebyshev.Chebyshev.cutdeg

`Chebyshev.``cutdeg`(deg)

  Truncate series to the given degree.

  Reduce the degree of the Chebyshev series to deg by discarding the high order terms. If deg is greater than the current degree a copy of the current series is returned. This can be useful in least squares where the coefficients of the high degree terms may be very small.

  Parameters : | deg : non-negative int The series is reduced to degree deg by discarding the high order terms. The value of deg must be a non-negative integer.
  Returns : | new_instance : Chebyshev New instance of Chebyshev with reduced degree.

  Notes

  New in version 1.5.0.
