What is the favourite or best Scientific calculator use by NA and designer?

[Wellydeckhand]

There are so many brand and type of scientific calculator, err...... I was quite amazed when I need to buy one for design calculation boat. I know we can use almost all calculator, but which are the favourite or best scientific calculator use by N A and yacht designer?

If you got a picture and some detail about it abilities than normal calculator in term of ship work would be a boon.

Casio grapical calculator is what I would recomend.
It can draw cures and you can store programs on it.
It has both square and cubic root.
With that and a tecnical formula collection you can calculate everything from dopler and turbine effect to resistance in electrical circuts and stabilety off hull's.

I would be suprised if it's no freeware download calculators on twocows.com or something

If you download opera 9 http://www.opera.com/download/get.pl?id=27903&location=133&nothanks=yes&sub=marine
it contain widgets and there you can chose calculator, but not that advanced yet, but I think it would come when becom more popular.

No calculator can match spreadsheet software on a PC.

I liked my TI-59 in the 80's, and now use a Hewlett-Packard 20S (regular Algebraic entry, notr RPN). I actually have 2, one at home and one at work, so I don't have to re-think how to use one or the other.
But, as someone said earlier, it vcannot match what you can do on your PC with a spreadsheet, and Rhino has its own built0in calcualtor now...

I typically keep three or four math tools handy... here's my favourites.
Hand calculator, carry it everywhere --> Casio fx-991 series
Spreadsheet --> Excel or Quattro
Mathematics suite --> Maple 9.5/10 (really powerful, but really pricey though)
Plus a few little applets like Convert.exe, etc. and sometimes an equation solver like EES.
Not a fan of graphing calculators. They're bulky and complex and expensive, you can't carry them around easily, and when you're at your desk you have a computer handy anyway.

I have had a TI-65 Technical Analyst for years.When you don't have a computer and a spreadsheet available it can't be beat. It has all the usual scientific functions plus it has built in conversions from Eng. to Metric, it's got a built in count up timer, and count down timer, and much more. I don't think these are available any more but I'm glad I have one. Other than that If I had to choose I'd get one of the programmable calculators that does graphs and has a cable link to your computer.

[Wellydeckhand]

Yup, HP made some of the best financial calculator, for my calculation of cost and lending from banks.......... a Casio 9000 for graph.

But I was told there is a casio version special for shipyard and designer calculator?

HP34C -> HP11C -> HP48GX -> HP49G+
The best is to have an equation solver in which you enter equations with n unknowns, (n-1) known parameters and get a result for the remaining unknow.

I am addicted to my HP48 GX, had it for 100 years can't imagine life without it.

[MikeJohns]

I went through school and my first degree with a slide rule, now I too am utterly addicted to an HP 48GX. Most engineers I know share the HP addiction.
Had mine around 10 years still haven't read all the manual :)

On a PC I use Excel a lot, but for anything that needs more complex maths I would be lost without Mathcad.

[spank]

Without a doubt...HP48GX. Got me through university physics, calculus etc. and it one of the few items that I always know the location of at all times. It is the only device the I still have the manual for. RPN is superior too.

[redcoopers]

HP48GX seconded. I also have a TI-89 and HP49, but the good old HP48 is still my favorite.

My theory is: if you need to do anything more complex than number crunching, use EXCEL, or MATLAB, or anything else PC. Otherwise, the tactile feel of the HP48 makes it simple and intuitive for arithmetic.

I found this powerful calculator very useful, it can split screen for graph and do almost everything including finacial calculation. The big plus is you can use your 1 gig SD memory card to store your computation and formular.

Looks expensive. USB inteface on a calcuator? Whatever floats your boat... got a model # for us?

[westlawn5554X]

This calculator work on batteries, have external electric cable hole, USB cable included, SD memory slot without a card.

The model is CASIO fx- 9860G SD.Price I bought at around US$90. check it out internet google.

I have just bought this a month ago for my studies and still playing with it. I am hooked to its financial capabalitity to count cost and bank, with preprogrammed equation.

It has two version, fx- 9860G without SD but faster, fx- 9860G SD with ext. memory .

Westlawn,

You told me u were broke buying all your stuff, i understand now, although the CASIO fx-9860G SD really was a bargain (where did you finnd it for that price?) You obviously own a computer and could have saved yourself this expence (see No3 reply in this post).

[westlawn5554X]

Yes, when your at the drafting table or out on a cafe table discussion and fight on the size of the boat do you bring a notebk or a calculator? I imagine I will have field work and project later on with my CASIO brain.

I was searching for HP outlet and found a CASIO instead, the market is like 9:1 over Casio : HP. I look for the type with the memory freedom model.

I dont know European market. Try the biggest shop you can find that is not in a MALL.

[adesrotours]

Hi !

Could you tell me where can I but it ?
I'm looking for it in internet but I can't find it to buy in the States.
Thanks.

Adrián.

[westlawn5554X]

In Asia it cost in distributor sale at US$100 without delivery. I know this is fresh from the oven model, I too can find the site just from the shop in my country's capital, I am living isolated area.

Happy hunting... Slide Ruler are also calculator!

Just a Question Guys

Just lets say I bought one of these fandangle you beaut calculators which does all these things, do you still need a sound background in maths that is required to complete any design course on offer?

[westlawn5554X]

Sometime we do need a brain, I am still looking for a branded one:)

Yup. Calculator's dead useless without the knowledge that tells you what to put into it, and what to make of what it spits out.

[joz]
