One thing you need to know is that Excel trig functions accept radians as arguments, and the arc trig functions return radians. No exception. If you want to get the same results on your 35S, you have to make sure the MODE is set to RAD and that all of your angles are converted first to radians in both Excel and the calculator. Am I missing something here? I think you believe there is a serious bug in the 35s trigonometrics. Apart from the cosine bug near 90 degrees, I don't think there are. I think you are simply getting bogged down in going back and forth between radians and degrees. This is, respectfully, a high school math issue, not a calculator or Excel issue. Sort that out and all of your results should fall into place. ▼ Vincze Senior Member Posts: 376 Threads: 35 Joined: Jul 2007 08-15-2007, 03:18 PM No, I know problem not with calculator, but with me.

Les Les Wright Posting Freak Posts: 1,368 Threads: 212 Joined: Dec 2006 08-15-2007, 03:12 PM Here is my final hint, and then I am going to let you wrestle with this yourself: ```1. Put the calculator in radians mode 2. Enter LAT1 3. Convert it to decimal mode via HMS-> 4. Convert those degrees via ->RAD 5. Store it in a variable or write down the result (which is LAT1) in radians. 6. Repeat 2 thru 5 for each of LAT2, LON1, LON2 7. Compute your desired angle with your formula. It is in radians, and should agree with Excel 8. If you want to see the result in degrees, execute ->DEG ``` Alternately, you can keep the calculator in degree mode and skip steps 4 and 8 and you will get the result in degrees. For Excel to agree, compute everything in radians but change the result cell to =ACOS(SIN(Lat1)*sin(Lat2)+COS(Lat1)*Cos(Lat2)*Cos(Lon2 - Lon1))*180/PI Les Edited: 15 Aug 2007, 4:09 p.m. Stefan Vorkoetter Member Posts: 217 Threads: 21 Joined: Aug 2007 08-15-2007, 03:53 PM There's a difference between converting to radians, and being in radian mode. When the calculator is in radian mode, it expects all arguments to trig functions to be in radians, and it returns the answers to all arctrig functions in radians. It does not automatically convert numbers you enter from degrees to radians, because it has no way of knowing that the numbers you are entering are in degrees. So if you are in radian mode, you must convert all your degrees to radians before using the trig functions on them. The ->H.MS and H.MS-> keys have nothing to do with degrees vs. radians. They always convert between hours/minutes/seconds and decimal hours (or degrees/minutes/seconds and decimal degrees). Since aviation formulas are generally intended to be used in degrees, just leave your calculator in degrees mode and do everything in degrees. Forget about radians. In Excel, you still need to convert to radians, and then convert the answer back. Excel is permanently stuck in radian mode.

That's actually an interesting problem. Why is this acting diffently from the BIN/DEC/HEX mode? With these modes, it's changing the display of a number to a different base. Same thing, it's still the same complex number whether we are in x+iy or r,theta display. What if when we change mode, it does the DEG/RAD conversion? Would that be an improvement? Any thoughts? ▼ Stefan Vorkoetter Member Posts: 217 Threads: 21 Joined: Aug 2007 08-17-2007, 11:50 AM Because BIN/DEC/HEX mode and real vs. complex affect all numbers. Degrees vs. radians affects only angles. Consider calculating the value of 2+sin(45). You'd enter: ```2 ENTER^ 45 sin ``` The calculator should obviously not convert the 2, since it's not an angle. As for the 45, you might want the calculator to convert it from degrees to radians if you're in radian mode, but how is it supposed to know that you've entered it in degrees? Perhaps you meant 45 radians!

It makes me wonder what high level programing languages do as well, as I have never really tested either, but I would think it would be same as Excel. In mathematics, the trigonometric functions are always defined in terms of radians. This is because radians are the most "natural" unit for those functions. For example, in radians, d(sin(x))/dx = cos(x), while in degrees, d(sin(x))/dx = cos(x) * pi / 180. High-level programming languages all follow this convention; this is true in BASIC, Pascal, C, C++, Java, and Excel, just to name the ones I'm personally familiar with. This means that Excel doesn't convert its arguments to radians on the fly; it treats the arguments to its trigonometric functions assuming they are in radians. The only times when arguments get converted "on the fly" is when you are using trigonometric functions on calculators, while they are in DEG or GRAD modes. I think what got you confused was when you were trying to use the Great Circle Distance formula, where you actually have *two* conversions to worry about, namely the conversion between degrees-minutes-seconds (which is used in navigation) and decimal degrees, and then the conversion between decimal degrees and radians. As long as the calculator is in DEG mode, all you need to do is the H.MS -> H conversion before applying sin or cos; if the calculator is in RAD mode, you need to do H.MS -> H, and then DEG -> RAD, before applying sin or cos. - Thomas ▼ Vincze Senior Member Posts: 376 Threads: 35 Joined: Jul 2007 08-17-2007, 07:43 AM Quote: I think what got you confused was when you were trying to use the Great Circle Distance formula, where you actually have *two* conversions to worry about, namely the conversion between degrees-minutes-seconds (which is used in navigation) and decimal degrees, and then the conversion between decimal degrees and radians.

Yours is a land of remarkable, if not gifted people, so there is no such thing as a stupid Hungarian who should not post here. You are anything but stupid, Vincze, and you should keep posting. For occasional posters like me in particular and all the other contributors in general it is good to read from people like you. However, in the 1950s there was a "theory," so to speak, circulating amongst the non-Hungarian colleagues of some of the people I mentioned above: Hungarians are from Mars. The reasons: 1. They are very smart. 2. The Hungarian language is different from all the other languages in Central Europe (and presumably on Earth.) 3. They are like gypsies (the reason why they came from Mars in the first place.) You can find the whole story in "The curve of Binding Energy", by Roger (or it was Richard?) McPhee. The point is, beyond saying "stupid Hungarian" as a way to express one's inability to grasp the obvious, ther is no such thing.

Vincze, my friend, summarizing up all the previous posts, you are simply not allowed to leave ... we will not let you go away. ▼ Vincze Senior Member Posts: 376 Threads: 35 Joined: Jul 2007 08-19-2007, 07:16 PM Thank you my friend Nenad. It is nice to see you again. I take beating from calling myself stupid Hungarian, so I will no longer say that. I will call myself stupid American. ;) No, I just kidding, I think I smarter than stupid American... but maybe not smarter than smart American. I think I just dig hole for myself. ▼ Ed Look Posting Freak Posts: 801 Threads: 36 Joined: Nov 2005 08-19-2007, 08:04 PM Quick! Use your 35s and calculate the depth of the hole and the amount of thrust needed to get you out! :D ▼ Vincze Senior Member Posts: 376 Threads: 35 Joined: Jul 2007 08-19-2007, 08:16 PM I think my hole taking on water. ;) Gerson W. Barbosa Posting Freak Posts: 2,761 Threads: 100 Joined: Jul 2005 08-19-2007, 08:33 PM Hello Vincze, From some of your previous post, it's clear that most of your problems stem from the fact that your handbooks are written in English, rather than Hungary. You're right, manuals written in a language not our own sometimes look Greek to us (I wonder how the Greek would say that :-) I hope the following expresses this feeling correctly :-) ``` Once there was a freak Who was always up the creek. Surely knowledge-hungry Was this guy from Hungary. But, alas, his books were 'n Greek! ``` Don't worry about the word freak. Once someone said we're all freaks here. My knowledge of English is not better than yours, but I think this shoudn't be considered offensive, quite the other way around. I am just a guest here, like everyone else, but I ask you please to stay :-) Best regards, Gerson.

It funny what we think is normal sounding and what not. Yes you are right, reading English is a bit challenging at times. I can talk it well, but writing and reading have always been hard for me. My wife keep asking me why I try and get MBA since I have done well in life, but I want American degree, not just MBA. I'm sure I could get MBA in Hungary very easily, but getting degree in USA very hard sometimes. Anyhow, thank you for kind words my friend. ▼ Giancarlo (Italy) Member Posts: 223 Threads: 19 Joined: Jun 2005 08-20-2007, 08:49 AM Hi Vincze. Of course I fully agree with what others already said about the importance you ignore the *real stupid* people that sent you that e-mail, AND you go on posting whatever question you may have, and for a couple of reasons, at least: 1. often, those *stupid* questions make somebody else say to himself "that's what I would have liked to ask, but don't know if I ever would have the courage...So thanks to that Hungarian guy!" 2. you have not joined the forum since a long time, but did you notice how was lively and bright the debate after your inputs? Now, Vincze, my friend (I hope you don't bother if I borrow your nice expression ;-) and my neighbour (well, almost...) please keep on contributing with your "thirst for knowledge" ;-) Warmest regards. Giancarlo ▼ Vincze Senior Member Posts: 376 Threads: 35 Joined: Jul 2007 08-20-2007, 08:56 AM Giancarlo, my friend. I not mind at all you using my saying. We are all friends here, and I always think it nice to say to people. I will continue posting. I not notice one thing you said though, that everything lively after I post. I wonder why that is. I am just a humble man who want to be student of life. I know many things, but many I do not know. I assume when I die, and am blessed to meet my Maker, than maybe I will be gifted by Him, and know everything. Until then though, I am happy with only knowing a little.
