Graph Calculator Question


TheProphet

Recommended Posts

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!

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 :rolleyes: . 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.

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.

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.
