Dr. Jones, My mail box seems to have reached maximum capacity with the reciept of the attached email. I have cleaned out a bit and should have room for many more now. My question is: Is there a way to get the emails I missed, in bulk, to my email? Thanks, James...

Let a = an angle in degrees. Let b = an angle in degrees. Then a = arctan(0.40824829 / (0.292893219 + 0.0747 x n)) b = 150 - a Interval = (n x ((sin a)/(sin b)) - (sum of previous interval multipliers) ) x u New e-mail = njones@xxxxxxxxx Regards, Neville www.GeocentricUniverse.com -----Original Message----- From: jack.lewis@xxxxxxxxxxxx Sent: Sat, 6 Oct 2007 17:23:14 +0100 Dear Neville, Forget all the e-mails about the diagram. You have answered my problem except, is there a function I use to extend the perspective scale?
