sin(3F)                                                   sin(3F)



NAME
     sin, dsin, csin, zsin, cdsin - Fortran sine intrinsic func-
     tion

SYNOPSIS
     real r1, r2
     double precision dp1, dp2
     complex cx1, cx2
     double complex dx1, dx2

     r2 = sin(r1)

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

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

     dx2 = cdsin(dx1)
     dx2 = zsin(dx1)
     dx2 = sin(dx1)

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.  cdsin and zsin return the double-precision com-
     plex sine of their double-precision complex argument.  The
     generic sin function becomes dsin, csin or zsin as required
     by argument type.
