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.  dsin re-
          turns the double-precision sine of its double-precision ar-
          gument.  csin returns the complex sine of its complex argu-
          ment.  The generic sin function becomes dsin or csin as re-
          quired by argument type.
