where is 35s cos bug  Andrew Nikitin  10052008 It was mentioned that 35s cannot proprely calculate cos (and some other trig functions) in certain ranges.
Where can I find examples with an appropriate argument and erroneous result given by 35s? I cannot seem to find the bad inputs.
Re: where is 35s cos bug  George Bailey (Bedford Falls)  10052008 Do a Google site search like so: Re: where is 35s cos bug  Andrew Nikitin  10052008 Google finds numerous pages with a sentence "Cos(x) for x near 90 is dud". It also, surprisingly, finds this very thread. However, what I am trying to find is actual numeric example of X where cos X is calculated incorrectly by 35s.
If found mentions of "cos(89.999) bug", but my 35s says Edited: 5 Oct 2008, 10:39 p.m.
The HP33s/35s trig bug, tabulated  Karl Schneider  10062008 Andrew  Here is what you seek: http://www.hpmuseum.org/cgisys/cgiwrap/hpmuseum/archv017.cgi?read=123880#123880 The new HP20b gives all correct results, so I believe that the bug has been addressed, and will not recur.
