Graphing Calculators

[rusty bumper]

Hi all,

Can anybody recommend a good brand of graphing calculator for a trigonometry & geometry class? Will also be using it for quadrilateral equations, etc. too.


Thanks!

Re: Graphing Calculators

Most popular one and the one that our school requires is the Texas Instrurments TI-84. It used to be the TI-83 but the 84 is the newer one now.

We always used the TI's in highschool, and I had a TI-89 through college. The other popular brand is HP.

I'd go with a TI one. I had a Casio one and it died during my final exam.

Back in the day when I was in school, I worked for Target in the electronics department. At the start of the school years, we'd go thru cases of TI ones.

Does one really need a graphing calc for trig or geometry? In any case, get an HP 48GX if you can find one.

I used to have a Ti84 Silver, but it got stolen...so now I have a Ti83+

the only downside to the Ti's is they reset into Radians. Personally I find it harder to think in radians to I use degree.

For my high school the Ti89 is not allowed because it doesn't do a good enough job of round clearing (2nd, "+", 7, <-, 2 ,enter)

Re: Graphing Calculators

Id say TI 83, its like a standard now I guess, but now Im in college they wont even let us use them but the teacher will pull one out and use it so Im like.... what the..... nnnnaaawwww that aint right, and they call themselves professors with doctorial degrees

Re: Graphing Calculators

You can tell I barely used the 89 for "advanced' stuff.. what is round clearing?

And as Bluetooth points out, I never used a calculator for a math class in college....

Re: Graphing Calculators

round clearing clears your calc. of all programs and other apps. It can be disabled by a program called MIRAGE.

Ahh, just making sure students dont type stuff in.. but who would do that....

Looks like a scientific calculator would suffice for that class, but the course calls for one.

How times have changed!

Back when I was in high school, calculators were almost nonexistent.

Looks like Texas Instruments gets a lot of votes here.

What about the TI-86? Has anyone used it?

You mean they didnt use the abacus anymore...

I should say I have used the TI's since 7th grade really, when I had pre-algebra, probably have used the 82, 83, 84, 86, 89. But like others mentioned, in any class that required one, it was almost always a fancy adding machine. Only a couple real things were graphed. But maybe it is different for you....
