I'm an entering freshman so I figure I'll have to use it for a while. I'm use to a ti-83, so I can figure out some functions but I don't want to spend the entire course figuring out how to use it. I've heard that the ti-89 is banned on like the SAT, but will it be in future math classes? I have no idea where to begin! Thanks in advance.

what..i made it through all calc classes (calc 1-4) with a ti-83...i say screw thier requirements and stick to what you know best.

You won't be in the class forever. Just do your work now, and you'll forget all about it later on. (That's how I got through trig!)

....|&#92;\n....|a&#92; 15\n....|...&#92;\n....|___&#92;\n......8\n\nFirst, use SOH CAH TOA.\n\nSoh - sin=opp\n................---\n................hyp\n\nCah - cos=adj\n................---\n................hyp\n\nToa - tan=opp\n................---\n................adj\n\nIn this case, you know the hyp and the opp, so you would use sin.\n\nYou then want to substitute in the values\n\nsin <a=8\n...........-\n...........15\n\nDividing, you get\n\nsin <a=.5333\n\nIf you have the Texas Instruments TI-30XIIS calculator or similar, you will want to find the sin-1 key and hit it, filling in the parenthesis with .5333\n\nClick enter, and you get 32.2309 degrees, which rounds to 32 degrees

You are not going to find answers to your work.  The best you will find are similar problems and sites walking you through them.\n\nThere is also the option of looking for the teacher's edition through Amazon, but that can take a week or so and you would need to be able to make an online payment.\n\nLastly, here is the lecture, do your own damn homework.  Math sucks, but if you plan on taking any college classes, you will have to take at least two more math classes no matter what major you get into and will need to know what you are doing to pass.  Anyway, good luck.

SAT II 1C covers basically up to that point, knowing some trigonometry ooncepts wouldnt hurt. But if you mastered precalc then that means that your geometry and alg 2 skills should be alright.  Although, if you want a good score on the 1C test, its much harder, since many students that take the test do very well, getting a good score will be hard if you are at this disadvantage of not knowing more. If you have time, go for the other test, the one after it...

If you're trying to get into a selective college, or if you plan to major in something math-related, take the pre-calculus. If you're not planning to major in math or a science and you're applying to an average college, just do whatever you have to do to graduate from high school.

Both calculators can be found on the TI website.  You can get all the specs on both calculators there.  I do believe that solving nonlinear equations is possible on the 89, because it does have a computer algebra system.  The voyage is more powerful than the 89.  Sorry I don't know the exact website, but type in Texas Instruments and you should get there.  \n\nHope this helps!

All area, wherever you go..you will use that algebra for your work. For example, the simple one, if you are working in the service company, and you have to make a report of the percentage of total complaint you receive a day...\nYou have to use your algebra.\n\nDon't ever think it's pointless..., otherwise you will hate it and later on you will regret it, that you don't pay too much attention to that subject

(4,3) and (-4,-3)\nI think.\n\nCan't blame ya for asking about that one.  Trying to do that equation without a calculator before Calc III can be a pain since you don't get a shortcut in differentiating that type of  problem until late into Calc III.  It can be a pain even with a calculator without that shortcut due to the fact is doesn't balance easily either into a y=f(x) form.

hey, you can try the TI-Series calculators..\n\nThey are simple the #1 calculator on the market, same price for over 6 years now.\n\nI have a TI-89 Series and I can do everythign the mathematica can, except the mathematica programming. TI-89 does assembly and C programming.\n\nand you can send info from comp to the calculator..\n\nhttp://education.ti.com/educationportal/sites/US/productDetail/us_ti89ti.html\n\ntake a look at it

Mathematica is to symbolic calculus what the calculator is to arithmetic.\n\nIt is an extremely powerful tool that if used correctly can relieve one from the tedium of having to sift through the bookkeeping of solving a problem.\n\nOn the other hand, using it as a crutch by someone who has not yet mastered the basics will be harming themselves by relying on something else to do the heavy lifting for you.\n\nSo short answer, if you are working on a project and have developed a complicated model to simulate a system, it will be useful where a hand solution would be difficult or impractical. If you are looking to solutions to your homework, you will be harming yourself.

to make sure people like you don't get into college.\n\n---\n\nit's a nickname. my name could be GuitarBoy if I wanted, but I didn't, so there. and I was kidding. math wasn't "invented"; it was developed over many years.\n\nand yes, it is hard, I do alright in calculus, but it's still hard and it bugs me. I don't like it either.

I thought the rule was two of any level entry...I'll do a little research and see what I can turn up.\n\nLater: as I thought.  One website on the topic says "There must never be a lone subtopic. You cannot divide something into less than two parts; therefore, every A must have a B; every 1 must have a 2. "  See below for the website reference.  However, since Roman numerals indicate major topics, can you really write a decent paper that only has two main points/topics?

If it is anything like the TI-83 plus, you need to turn on DiagnosticOn. For the 83 hit [2nd][0] which is the catalog of all commands and scroll down to DiagnosticOn hit enter twice and then run the linear regression. I assuming they didn't change the calculator that much and that this wont work for the TI-84 plus.

Check with your school, and now for help.\n\nGo to the good book stores, and paper/computer supply places for their CD's - yes they have them on math, and CD's on SAT, and PSAT with actual questions and study on your computer!!!!\nAnd check online for the cd's for study...they even have foreign language cd's...........don't ever give up!\n\nIt's the best!...and was not available when I went to school.

1. the score is calculated by the college board.  you can take it as many times as you want, as long as you pay the registration fee.  when you send scores to colleges, they receive your whole SAT profile, including all the college board tests you've taken.  but don't worry, they usually just use the best ones.\n2. you can cancel your scores within about a week of taking the test.  after that, they're set.  but there isn't much reason to cancel them.\n3. the curve is just the way the college board calculates scores.  if in one month most of the students get a whole bunch of problems wrong, then they'll curve it to make the average score what they think it should be.  despite what people say, it really doesn't make much difference what month you take it in.  take it when you're ready, and not before.  remember to leave a couple of opportunities to retake it in case you don't like your score.\n\ngood luck.

I don't know what Anne is talking about, but what I do know is that you can indeed use your calculator on the Math IC, even though it's not necessary. Why are you taking IC though... here's an article about it that I found pretty convincing: http://admitspit.wordpress.com/2006/10/14/the-pointless-brother-math-level-1/\nAlso, here's another article from the same website about calculator usage on the SAT tests: http://admitspit.wordpress.com/2006/10/09/but-what-if-i-dont-have-a-graphing-calculator/
