Sinc

Sinc[z]
gives sinc(z).
  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • The argument of Sinc is assumed to be in radians. (Multiply by Degree to convert from degrees.)
  • Sinc[z] is equivalent to Sin[z]/z for z≠0, but is 1 for z=0.
  • For certain special arguments, Sinc automatically evaluates to exact values.
  • Sinc can be evaluated to arbitrary numerical precision.
  • Sinc automatically threads over lists.
