Calculus aint so tough assuming you know your trignometry :D

Im using a Casio fx-991MS :D

You have a calculator that does algebra :o! For three variables :o!

I didn't even know that such things existed. My school sells the fx-82MS now, but they had the fx-82TL when I started high school. I have a fx-100AU.

We've all always wanted to be able to key in an equation and get an answer, and we believed that it was impossible :'(.

I guess that a calculator that can do that wouldn't be "board approved" though and we wouldn't be able to take it into our exams though.

True. It needs to be "board approved"  I could have got the fx 3000d :drool: But thats not allowed as you can store formulas (predefined functions) in it.

I have that calculator cause i aint in school anymore. And doing algebra aint a big thing here. You should know how to slove the sums with all kinds of methods .... solving it is no biggy (with the calculator, else you cant finish a 3 hour paper even in 12 hours) With a calculator like fx-100d (The "basic" scientific calculator) it will take me 4-4.5 hours to do all the calculations ....

Hence there are only a few "board approved" calculators for the year you are in. As you goto higher grades and university eventually, you'll have to upgrade your "hardware" ;)

In school you need to know how to solve stuff .... we didnt have calculators approved by our board. No state in our country can do that :P But by the time you goto university, you are already so good at it, they dont care anymore :tongue:
