TI 89 Calculator: How do I transfer a single program from the calculator to the computer?
Q. TI 89 Calculator: How do I transfer a single program from the calculator to the computer? I am not trying to make a backup. I want to be able to copy a program I already manually typed into the calculator to edit on a computer, and then transfer back the edited version to the calculator.

A. You need to check if it needs a cable or if it has an infrared sensor and your computer would need to have one as well. I suggest that you take a read at its instructions because you may need to buy a cable if it is possible to do what you want to.

What kind of calculator should I purchase for school?
Q. Hello! I am just starting my education. I am double majoring in Biology and Chemistry. Which calculator should I purchase to help me through school? I prefer TI calculators. Right now I am thinking about either a TI-84 Plus or a TI-89 or the new TI N-Spire. I understand that any scientific calculator will work, but I would MUCH rather have a super cool calculator! I've just always been a fan of the TI graphic calcs.
Asked by Zane's Momma - Fri Jan 1 01:03:07 2010 - - 7 Answers - 0 Comments

A. I was a double in biology and chemistry and only had 1 calculator: TI-86 which isn't made anymore but is replaced by the TI-84 Plus Silver (I believe--I was told Plus and Plus Silver are different and I'm not positive which is the equivalent). I had friends that had the TI-89 and loved it as well. I don't know anything about the TI N-Spire though. Any higher level one like what you have listed should work fine but if you have experience with 1 model over another-I would use that.

How different is a graphic calculator compared to a scientific one?
Q. Does a graphic calculator still have the same functions on a scientific calculator, but with more? Are they about the same price or is a graphic one more expensive, and approximately by how much?
Asked by Deep - Wed Aug 12 11:57:04 2009 - - 2 Answers - 0 Comments

A. a graphic calculator DOES have the same functions as a scientific calculator. However, there may be some functions on the scientific calculator that you may or may not need. For instance, binary. octal, and hexadecimal number conversion are usually not found in a graphic calculator. A graphic calculator may help in more advanced courses, but it will not help with everything. I've taken alot of advanced math at the university level and I almost never used the graphing function of my TI-83, TI-86 or TI-92. Is it worth the money? that depends. I never saw any of my professors using a graphic calculator. They only used a scientific calculator. Good Luck

A. Hello! A graphing calculator is very important in Calculus. A TI-89 is actually the best. It is so much better than TI-84. I suggest getting a Texas Instrument because it seems like it is the most reliable. Get a TI-89, it is worth it because the function allows you to do anything. My teacher said if you have a Ti-89, you don't need to know anything... HAHAHA i agree...

How can I use a calculator to evaluate the trionometric function?
Q. How can I use a calculator to evaluate the trionometric function? Round your answer to four decimal places. (Be sure the calculator is set in the correct angle mode) I am so lost on how to do this. 43) Sin (pie/4)
Asked by Max - Tue Apr 14 19:41:07 2009 - - 1 Answers - 0 Comments

A. It depends on your calculator model. Scientific calculators means that you could have to convert the angle to degrees (pi/4 = 45 degrees). If you have a graphing calculator, there should be an option to switch between degrees and radians (on the TI's, it is the mode button). At this point, you should just be able to enter your answer as it is written above, parentheses and all. If you want to check your answer, it is (root 2)/2, which is .707107 This problem is easy enough to do by hand, which is a great way to reinforce your understanding of trig.

How do I make clear my calculator without getting rid of certain apps?
Q. I have a TI-84 Silver Edition. I want to be able to clear my calculator's memory without getting rid of certain apps. My teacher clears my calculator's before every test and I want to keep some apps so the test will be easier.
Asked by akdoanmg - Fri Jun 11 17:18:31 2010 - - 2 Answers - 0 Comments

A. I believe you mean programs. Just for clarification, an app and a program are two different things on the TI-83/84/Plus/SE calculators. I won't go into details about the differences, but programs will go under the [Prgm] menu while apps fall under the [Apps] menu. When you say your teacher clears the calculator's memory, I assume he or she simply performs a RAM clear. Most applications are archived, meaning they're located in Archive memory, and not RAM memory. Programs can be either archived (indicated with an asterisk (*) before its name) or unarchived. Unarchived programs reside in RAM memory, so that means when a RAM clear is initiated, it will erase everything there. To archive a program, simply press [2nd][+](Mem) > 5:Archive. Then, [cont.]

How does the ti-84 graphing calculator construct a probability plot?

A. They should be the probabilities (as a decimal). It just does what you would do: find the total frequency then divide the number of items in each interval by the total frequency [assuming I understood your question]

A. Ti-Nspire is a good calculator! I used a Ti-86 graphing calculator for most of my college calculus classes, but they've discontinued making those, and replaced them with Ti-89s. Profs will tell you which specific calculator they recommend you use in their class on the first day. Wait to hear thier suggestion; you might end up having to buy a new one every year!

How do you calculate logarithmic formulae without a calculator?
Q. I've searched a few texts regarding log functions but can't seem to find one that explains them in first principles. John Napier must have done them without a calculator and I'm guessing there is an algorithm that a calculator must use to calculate them. Can anyone help me? I should add, I'm not searching for answers regarding 'simple' log functions like log to base 2 of 32. I would like to know how to calculate equations such as log to base 10 of 64.
Asked by Matt C - Sun Feb 22 06:46:27 2009 - - 4 Answers - 0 Comments

A. There is no way to evaluate expressions such as log(64) exactly. This is an irrational number, and even computer programs are just ways we have of approximating the exact number. There are many other approximation techniques. Some include mechanical computers (like slide rules); others are graphical and involve the use of logarithmic or semi-logarithmic paper (they are in fact similar to the principle upon which a slide rule works). Some are purely mathematical... I believe someone already mentioned Taylor series expansions. For the 17th or 16th century, these would probably be the most practical and accurate techniques. For example, to approximate log(64), you would likely start by making the conversion log(64) = ln(64)/ln(10) via… [cont.]

How do I calculate nth roots without a calculator?
Q. How can you calculate something like the third root of 5, or 5^(1/3) without a calculator? For something like the third root of 8, it's obviously 2. Is there a trick for doing this without a calculator and/or any equivalent exact values that could be used?
Asked by Xedo the Cat - Sat Jul 11 23:48:09 2009 - - 1 Answers - 0 Comments

A. There's no trick, but there are techniques to approximate. For example, what is the square root of 30,000? Well, you know that the square root of 10,000 is 100 You know the square root of 40,000 is 200 So, the square root of 30,000 is about 175. (Actually, it turns out to be slightly more than 173) You can apply similar techniques to find nth roots.

Asked by laura g - Wed Jun 11 05:33:08 2008 - - 2 Answers - 0 Comments

A. If all you're answers are appearing in scientific notation, you would have to change a setting. However, if it's only happening for some calculations, it may be because you're calculator cannot express the answer without the exponential. If this is the case, you can't do anything about it but if you are looking to change the settings it might be called something like 'scientific notation' or 'standard form' or 'EXP'. Good luck.

Asked by WishingUhappiness - Sat May 2 02:16:16 2009 - - 1 Answers - 0 Comments

A. Every time you install TI-Connect, you have to make sure it's able to detect your calculator. This can usually be done by opening up TI-DeviceExplorer, and seeing if it can detect your calculator. If not, then try uninstalling and reinstalling. If that doesn't work, it probably means you installed the wrong driver (i.e. plugged in the USB cable before installing TI-Connect). You then have to open up Device Manager in Windows, delete the appropriate driver, then reinstall everything. It's a pretty cumbersome process, so good luck.
