Taking a grad level math class - ti-92 calculator - woo hoo

episodic

I'm taking a graduate 'survey of calculus' class.

When I was in school for my undergrad and my grad degree before (not math), even in math classes, we were never let near calculators.

I've bought me a ti-92 edition calculator - and this thing can slice, dice, and chop - why were these not invented my first go around in school, I might have got a phd in math had I had this baby.
 
Yeah, newer calculators rock. I especially like that there are memo and notecard functions that basically allow you to crib sheet without anyone ever knowing. 😎 I've scored nearly perfect in every math final, as well as my econ finals, because pretty much every important formula or note was on my calculator...which they graciously let us use.
 
Yeah, CAS calculators pretty much do everything. I've never had a college level course allow anything above a TI-83.
 
Really? I've never had a course prohibit any of them, except one particular model that apparantly had some error on certain types of calculation.
 
I like my Sharp D.A.L. EL-510R

It's only $10, but you can do stuff like this on it in one shot:

269-3(5*4-6)^2-6/8

It's a lot easier than having to do this on a regular calculator

269-3(5x4-6)^2-6/8
269-(15x12-18)^2-6/8
269-(162)^2-6/8
269-26244-6/8
269-26244-.75

=-25975.75

I think I have it right

You think THAT'S impressive? How bout

solve(d(X^6+2x^2+3x-2 + cos(x+tan(x))/sin(x^2-2tan^2(x-3)),x),x)
 
Ti 83+ is the highest they let my calc class use

wont let us use Ti-89, as it has the algebraic systems built into it so it can solve any formula with a click and requires no work or knowlege 😛.
 
I meant spending Ten Dollers is better than spending a hundred Dollars.

I have to do the problems by hand for tests and quizzes, but on the SAT's and the AP exam, we're allowed to use it.

It's not that I don't know the math - life's just a LOT easier when you never have to do algebra 😉

I am getting -1279/4 too

I have a Ti92, it's too clunky for me. I prefer my Ti89.

Same here. It's all about PEMDAS.
 
Well, I don't have my Sharp with me at the moment (Sitting in my locker 1h15 away).

You can do boobies on it too 😛

JESUS CHRIST, AND YOU PASSED ELEMENTARY SCHOOL?

= 269 - 3(14)^2 - 6/8
= 269 - 588 - 3/4
= -319.75

First: () [], etc.
Second: Exponents
Third: Multiplication / Division
Fourth: Addition / Subtraction

We call it BEDMAS at my school... I'm positive I did that right...

Why is he distributing the 3 before doing the operations inside the parentheses and the exponent? Did I miss something?

I can write, "Codegen sucks at the math" on mine.
