sin(3F)                                                   sin(3F)



     NAME
          sin, dsin, csin - FORTRAN sine intrinsic function

     SYNOPSIS
          real r1, r2
          double precision dp1, dp2
          complex cx1, cx2

          r2 = sin(r1)

          dp2 = dsin(dp1)
          dp2 = sin(dp1)

          cx2 = csin(cx1)
          cx2 = sin(cx1)

     DESCRIPTION
          sin returns the real sine of its real argument.  returns the
          double-precision sine of its double-precision argument.
          csin returns the complex sine of its complex argument.  The
          generic sin function becomes dsin or csin as required by
          argument type.
