Hi all,
Jon has just alerted us to a typo in ps 3. In part (b) ii), we
forgot a minus sign. An updated version has been posted to the
website. I've send another email to the list with the new version
attached, but that seems to be caught up in the mailing list's
spam filter...
Have a good weekend!
Holger
