gives the Chebyshev polynomial of the first kind .


  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • Explicit polynomials are given for integer n.
  • .
  • For certain special arguments, ChebyshevT automatically evaluates to exact values.
  • ChebyshevT can be evaluated to arbitrary numerical precision.
  • ChebyshevT automatically threads over lists.
  • ChebyshevT[n,z] has a branch cut discontinuity in the complex z plane running from to .
