professor said only scientific calculators allowed wtf?

Calc II is integration? If so your calculator won't be much help anyway.

Havn't seen the TI-89 then have you.


Anyway, OP, suck it up and do the work. Most of the rest of us did.

Apparrently not. FYI, NatePo, the -89 does symbolic integration.

Wait, you need a calculator for calculus? As dumb as it sounds, I thought the calculus classes required the least calculating of all my math classes.

Agreed.

We were able to use scientific calculators in my class so we could verify our answers but that was about it.
 
As far as I know, my professor will let you use any calculator you want as long as you show your work.

hahaha i like this response 😀


yeah.. for a LOT of calc you dont need calculators. calc II is no exception
 
this is an old thread who bumped it?

anyway i'd like to take this chance to reiterate the OP is a doofus and a n00b. 😀
 
I have gone from geometry (IIRC that's when I first got a ti-83) through differential equations.

I only use it for parametric crap and simple arithmetic when the numbers get above 4 digits.

 
We were allowed to use scientific calculators only, but they were pretty useless as every answer was some variant of +/- 0, 1, 2, 1/2, 1/4, 1/8, and any of those numbers times pi. Oh, and maybe sqrt(2) and sqrt(3) were there as well. The only time you'd ever use a scientific calculator is if you were too nervous to remember what sin(pi/2) was or something.

hehe, this cracked me up. if i remember correctly, graphing calculators would not have helped on my calc exams because they were all proof-ish questions.

same here...with some variation of pi😛
 
even ill admit, ti-89 helped me pass calc2. its not that im an idiot, its that i seems make minor mistakes. i would use the ti-89 to check my answers or give me a hint if i was stumped. 99% of the credit given was for showing the work, not the answer.

was i using the calculator unfairly ... probably.
 
My math classes so far (calc I, calc II, and currently calc III - multivariate) do not allow any calculators. It's better in my opinion to not depend on a calculator anyway, since entering in all of the symbolic equations takes too much time, and attempting that on an exam in a hurry would cause more mistakes (for me at least) than doing it on paper.

At my school, the linear circuit analysis class doesn't allow calculators (for cheating, supposedly), but at least they're nice about picking convenient whole numbers or easy fractions. All of my other classes (physics, mechanics, chem, etc.) have allowed anything that doesn't have a QWERTY keyboard. The 89 is great for taking cross products in three dimensions and solving large systems of linear equations. 🙂
 
I had to go out and buy a scientific calculator last month for my Gen Chem 1 test.

I found it funny that I went through 4years of hs and 4years of college (with chem, phys and calc) with a TI-83/89 and only when I go back to school for prereqs for grad school do I need a non-graphing calculator.
 
A friend of mine, formerly a teacher in my school (now teaches at Buff State or Univ of Buffalo; I forget which one) was telling a story at last year's Christmas party about a bunch of kids who passed Calc I in their high school with flying colors, but they were taking it again in college for an easy A - they hadn't learned a bit of calculus in high school - all they knew was which buttons to push on the calculator. They could get the correct answers with a calculator, but were unable to show any work. They couldn't comprehend that showing the work was showing that they understood what was going on. F's for the entire group. So much for the easy A's.
 
Ti-89s can basically do the test by themsevles, and a Ti-83 can do a lot of the same things with a little love. Graphing calculators slow down your learning of the material if you become dependent on the material. Also derivatives aren't that bad, wait till you get to massive integrals, I seem to remember some integrals taking pages of work to complete.

At least you get the satasfaction of a (hopefully) simple answer at the end!

There's more satisfaction as the teacher to make some sort of elegant substitution, reducing the amount of work to 3 or 4 lines 😛 🙂 "Of course, we could do it your way too."
 
how bout you really learn math this time around instead of faking it with the calculator?

No calculus problem requires a calculator.
