SIN(3F)                              SysV                              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 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.
