I had to demonstrate a bunch of ways to solve this once. There are various series expansions (which, mericfully, I forget) that will generate a correct answer with enough iterations. (There are some straightforward ones that work fine if the oribit itsn't too eccentric). -- David Scheidt [email protected] _______________________________________________ GurpsNet-L mailing list <[email protected]> http://mail.sjgames.com/mailman/listinfo/gurpsnet-l
