HP35s Equation Mode



#2

I know what 2*2 line solve equation is, but how does one enter it? I try and hit ENTER, XEQ, etc, but nothing happen. I not see anything in manual that talk much about. Can someone please help.

Press SOLVE.

Edit:

In the Manual: 7-6, Solving built-in Equation

First, it will help you if you go to this page and download all the HP 35s learning modules. Quite a few questions are addressed in them.

35s learing modules

Second, there is a specific learning module on using the linear equation solver.

Good luck!

Thank you very much.

One thing I curious about. I thought I saw (maybe I misread something) that there were hundreds of built in formulas. Did I miss something?

There are two built-in formulas (2x2 and 3x3 linear system) and 42 physical constants in the 35s.

In New York Times today, they even had a bit that said the fiollowing:
Quote:
"The 100 built-in functions make the programmable calculator as handy a tool as it was when engineers wore bellbottoms. But one other thing has changed: the price is $60."
My question still is, what are these built in functions?

#8

Functions like:

Sine

Cosine

X^2

divide

etc.

Ok..... now I feel like a stupid Hungarian. Yes, those would be them.


#10

:-) Don't say that! You are the almost the only Hungarian I know, but if you are even remotely "average", they are a very smart nation of people!

Well thank you very much Gene. My Sicilian wife tell me that I am abbey normal sometime, but she mostly joking (I think). My son tell me I sound stupid when I talk but I have to remind him that I grow up in Hungary and I no think in english so it take me a little to translate. My goal this year to make my english better and not so choppy. If I take my time in writing, I think I can do.

Many Hungarians are smart, except when we drink Pálinka, and then we can do some stupid things. I always stay away from that stuff as I remember my grandma used to put a shot of it in her wash water when she would scrub her floor. She would say it would help take wax off the floor. But that a whole nother story which off topic so I will not bore you. You may know some famous Hungarians such as Ernő Rubik, who invent Rubik cube, Leó Szilárd és Edward Teller who both work on Manhattan project. Actually, they say Teller was the father of the hydrogen bomb. I think they are all smarter than me though.

Vincze,

I wish you the best of luck with your English! I promise that you speak English much better than I speak Hungarian (which is to say, not at all ;) ). But I studied Linguistics in university, and I greatly admire the Hungarian language. It is a very interesting language indeed. You will be lucky to know both English and Hungarian (and maybe some Sicilian, too!)

Isn't it the case that Hungarian and Finnish are related to each other, and to no other modern European language?

Howard

Hungarian, Finnish and Estonian (not sure)?

Howard, yes a little a like, as I believe both are uralic in nature. but I don't know finnish, so I really can not say. I know in magyar (hungarian), almost all words have emphasis on the first syllable, I am not sure if finnish is the same or not. I think they may have all originated from the same group of people way back in time (some place in Russia), and maybe a common, or shared language components. In magyar, we do not assign gender to things as much as other European languages do. I know in italian, for example, certain words are manly and certain words are womanly. Also do not normally have possessive pronouns. This was hard for me when I first came to USA as you use possessive pronouns quite a bit.
