Greetings,
Just was astonished to find out in useful links, Calcs, in sub-calculation named Trig., that cosine 90 deg=6.12... It is not what I was taught in school. ;> I was indoctrinated that cosine 90 deg. = 0. Live and learn. ;> ;> Definitely, some kind of glitch. I'm checking other sub. calcs. But a warning that all results from those calcs should be kinda checked for "sanity." I hope this was The only glitch.
By the way, I opened those calcs with Google Chrome.
