I just bought my new HP33s. Anyone could tell me how to input Deg-Min-Sec in angle? am trying to find the button to input say 57 deg 25 min 10 sec but there's no where and even in the manual didn't specify. Please advice

 
buy a casio FX-115 - either model (MS or ES) is under $20 - its not too late - that is my advise to you

Stop it! Don't hate the RPN just because you can't understand or master it :)

To answer the question...


Code:
Time Conversions
Values for time (in hours, H) or angles (in degrees, D) can be converted between a
decimal–fraction form (H.h or D.d) and a minutes–seconds form (H.MMSSss)

Straight from the users manual...

 
The HP33S SUCKS. I have been a "HP fan" ever since getting my HP32S almost 20 years ago. I never even considered going with anything other than an HP because of the QUALITY of my "20 year old HP32S."

Heck, I figured it might be time for a "step-up" to a newer model....

WHAT a MISTAKE. The HP33S was a TOTAL WASTE of money. Several of the keys have actually gotten "finicky" after only a year of use. I was loyal to the "brand," BUT HP was not "loyal" to the quality of their own product...

I haven't quite smashed my HP33S yet, but at least I no longer HAVE to use this POS ever again....

GOOD Luck!!

 
Jude, I hate that HP calculator so much! I actually bought the casio one later on because of issues like this! However I did learn how to convert angles back and forth.

I guess the easiest way to explain this is with an example.

Lets say you want to convert an angle of 10.5 deg. to Deg. Mins, and Secs.

Well you type 10.5 then you press the purple button and -->HMS.

You'd get an answer of 10.3000 which translate to 10deg 30mins 00secs... Yea I know retarded but that's what it is!

If it's the other way around then you'd type your 10Deg. 30Mins 30Secs as 10.3030 in the calculator then press the green button and then ---> HR. You'd get 10.50833!

I hope this helps!

 
Doh! I wish this thread had taken place a day earlier. I have a casio and I forgot that it would convert degrees to decimal degrees. I was doing it manually yesterday (on my Casio). Oh well, not a big loss.

I advise purchase of a nice, shiny new TI-30Xa, one of the finest calculators known to man.

33s can be set to RPN or "regular."

 
I've never been a rpn guy, but the 35s looked like a much better calculator for the exam than the TI's (I already had 2 TI-36's). I picked one up, ran it in algebraic ("regular") mode, LOVED IT!

 
I was a long time HP-48GX user so I picked up the 33S for the exam. For basic stuff it works OK but navigating the stack stinks, and the rotating 4 stack is limiting. The worse thing about it is how complex numbers are used, you have to memorized which one of the 4 stacks is real or imaginary and use a different key to perform it. If you are electrical like I am I reccomend picking up the Casio also. The complex operations are much better and it also has a 2 or 3 simutaneous equation solver built in. I think I used the casio around 75% of the time on the test.

Yeah... but I can't imagine there's anyone that like the form-factor of the HPs better than other options. The *only* saving grace to the current HPs that are usable is the RPN. Still, for those of us that prefer RPN, it's worth the trade off.

 
^Agreed. However, if your an RPN person, the 35s is a much better calculator. For electrical use, it does a much better job with complex numbers than the 33s.

:2cents:

 
Another recommendation for the Casio FX-115ES. It is the closest you can get to a Graphing Calculator based on all of the features.

I bought a 33s for the exam and don't use it at all now. So I switched the RPN off and my wife now uses it to balance the checkbook. Otherwise, the old 33s would be a paperweight - probably a poor one.

 
^ My 33s currently resides in a pocket of my flight bag. I might use it twice a year. I picked up a 35s and it's now my "daily driver".

My poor ten-year-old can't use a regular calculator! It's RPN or nothing for him. Does that count as child abuse?

 
Since I'm in the same boat as your kid, I'd consider it good parenting! :D

Good call. I took an FX-115ES and an HP35S both to the exam, but hardly used the latter. I'm a long-time RPN guy, but managed to get by with the Casio for most of the problems. The main thing for me was that it has a much better display than the HP.

I don't have to take the exam again :) , so both are now "retired" and it's back to my old trusty HP 48S for everything from workplace calculations to balancing my checkbook.
