Exactly, there must be someone you can borrow it from. To everyone, you need a graphing calculator for pre-calculus. Not a regular. You could do without, but the immense time you would lose will only let you get one question right. Your name. (Exaggeration) I'm thinking you're a high schooler since Pre-Calc isn't a necessary course for college. Just ask someone who takes trig or geometry or even algebra since thats when they require you to have one.
Maybe you're so well prepared you won't need one...but just in case ask to borrow one
Maybe *you* didn't. In most countries profesors teaching advanced calculus and other math related subjects (discrete mathematics, statistics, advanced algebra and geometry and so on) do not allow students to use calculators, mostly because many calculators can calculate integrals, derivatives, can graph and so on and the purpose of those classes is to teach you to do it yourself! I find it truly amazing that in an advanced country like USA and in subject like precalculus they not only allow but also require the use of calculators.
39- In my AP calc class, we are never allowed to use calculators, because, as you said, the point is to be able to be able to do everything on your own. However, just like OP, we were allowed to use calculators in my pre-calc class, as the cosecant of 7, for example, is not something that is easily calculated, and spending time calculating it is just a waste. Instead, we were permitted to use calculators to calculate values such as cosecant of 7, but we had to show all of our work. I am sure this is how OP's class works too.
In IB math exam is divided into three papers - you are allowed to use a graphic calculator in two of them and you can;t use one in the other one. Assessing different skills, basically. What is wrong with using calculator anyway? It's the thinking that counts the most, the calculation itself is of secondary importance. (Sure, the misplaced comas and so on are important in the real life projects, but for the exams? One point only for the correctness of the result, the rest is how you come up with the answer).
How the bloody hell did you get "hate the America" from my post? :P I think it is a very advanced country and many of the best universities are there. I've been there countless times, both for work (yes, legally, in IT field) and pleasure. Not everyone out there is to make fun of your country, so please don't give people any more excuses.
If Newton could do it without one, so can you! On second thought, you might just want to make sure you have everything next time.
You didn't calculate a good exam plan, OP, but I won't go off on a tangent...
Can't resist... must resist... It's a sure sin of memory loss if you forget your calculator, OP. I mean it's pretty irrational to forget that it is an integral part of your success, you'd think the thought of bringing it with you would be recurring. It's pretty primitive of you to do this with mental maths, the numbers won't add up, and it's just plane silly to try.
They don't have calculators for students borrow? That's a trifle odd, isn't it?
I study economy, and we're not even allowed to use a calculator during exams...
