Graph Calculator Question

[TheProphet]

Hi,

 

Im in need of a calculator now! So i'd like to hear what u Math guys choice would be in my case!

 

I'll be Studin untill reachin a Master in Physics (i belive it corresponds to this in England and US, Around 4 years od education.)

 

Currently im lookin at the Texas Instruments nr 83, 84 and 89. The only one else i've found was Hewlett Pacards 49G+, altough then the TI-89 seems liek a bether choice! Comments most welcome!

Currently im lookin at the Texas Instruments nr 83, 84 and 89.

I myself use a TI-86, and I would suggest that particular calculator since it does a great deal, with the exception of symbolic calculations. I find that using a calculator that does symbolic calculations tends to lead to mental laziness, and eventually one is solving one-variable linear equations with the calculator . However, if you can avoid this pitfall I suggest you get the TI-89, or the TI-92+, since they have a fair variety of advanced tasks, such as 3-D graphing. I recommend that you don't get a TI-83 or TI-84 since the syntax is rather arcane, and many Calculus operations that one may like to peform, such as numerical integration, are not possible to perform on either of these calculators.

 

Unfortunately, I have no experience with HP calculators, so I cannot comment on them.

TI83+ silver eddition

I myself think that TI-83s are not the most advanced, they are slower, and the more powerful TI-89 or TI-92 sounds suitable for college. TI-83s or 84s are not as advanced, and are more suitable for junior high or high school.

grrr, they are fast if u have an 83+ or 83+ silver eddition. fun for video games.

[Cap'n Refsmmat]

He's in college. He needs all of the advanced stuff, not just games.

My 83+ Silver isn't as fast as my 92

[ydoaPs]

u can't get "rape" on anything but 83

I don't think any Graphing Calculator is as good as the Maths software currently available to Universities.

 

Mathematica, Maple etc. >> Graphing Calculator anyday.

What is the firm of Ti? Casio?

[ydoaPs]

no. ewwwwwwwwwwwwwwwwwwwwwwwww. casio sux ass. TI means Texas Instruments

[NSX]

I have a Casio Scientific calculator.

 

It gets me by.

[ydoaPs]

why. i used my friends' before and they are impossible

[Cap'n Refsmmat]

I had a Casio and it just fell apart... apparently they are of low quality.

A TI-83 has zillions of functions, more than any plain old scientific calculator.

[Primarygun]

How much is Ti?

[ydoaPs]

it depend what you get. my 83+ was 90 dollars

[pulkit]

I have a casio, and everyone in my college has a casio, no-one uses TI here. It seems to be more than sufficient for our needs. You don't acctualy need more than about a 100 functions, which pretty much every scientific calculator has.

 

I actualy never felt the need of buying a graphic caluculator. You always have computers to draw graphs for you.

[Primarygun]

My calculator is sharp in firm.

It is without function , quartratic ..................

Therefore, I am going to buy a new one with my prize money:)

i saw ti-83+ on sale for $75 a few days ago

[jordan]

I've recently seen someone with a ti-84+. It seems that ti has put out an upgraded model and that could account for the fact that I too have seen many 83+'s in the paper for around 75$. I've not actualy got to play around with the 84+ to see what's changed.
