I've bought a 17bii and programmed in the trigonometric equations in the posting by Bruce Maguire. I've got the SIN+ COS to work along with the ATAN but I can't get past INVALID EQUATION with the ASIN and ACOS. It's probably my typing but after nearly a week, I'm going nuts. I've tried to contact Bruce but the email address was rejected.
I've noticed that there are a couple of oddities (typos ?) in the listing and wondered if anyone could help ?
There seem to be 32 "( " but only 31 " )"s and there are two "=" where they should be ":"'s (?). My ability to programme the 17Bii is very limited so thanks for any help from someone who has got this to work.
Regards
Charles
