dist/dir into x/y coords?

[Grendel]

First, thanks for taking the time to check this question out!
  :-\
My question is how to calculate x/y coordinates from a direction (in degrees);  lets say the player sees something, and uses his compass to determine that the something is at 45 degrees (or a script uses GetDir to find out), and 1000 meters away.  How do I calculate the direction and degrees into x/y coordinates?  I've tried looking at some scripts that I think are doing this, and it uses Sin and CoSin functions (which is beyond my current level of mathmatic ability).  I would really appreciate someone who could show me the correct equation needed.

I did some more digging and I think I'm on the right track, but I'm not positive. would this work?

_xtarget=_xplayer + (_targetdistance * (sin(_playerdirection)));
_ytarget=_yplayer + (_targetdistance * (cos(_playerdirection)));

Answered my own darn question...
Did some trial and error using the windows calculator, and it works...
so if anyone needs a calculation for, say, polar plot artillery missions - that would work.
