No. Get some money and stop buying second hand products. Sure, if it will work for you. Buying a used calculator may be a good way to save money. Be sure to make sure that the calculator works and is not damaged, though.

The square root button is about the "x2" button. Press 2ND and then x2 to use it. If you want a cubed root, press MATH and select 3âˆš(. If you want any other root, press MATH and selcect xâˆš. For example, to find the 5th root of 32, enter 5xâˆš32.

The on button is in the lower left-hand corner. It should say ON on it.

Assuming you're talking about the Texas Instruments series of calculators - it has a USB connector - you just need the relevant cable.

If you are trying to graph something, it is probably because a stat plot is on and one or both of the lists is it using is blank. This error will also occur when you try to access a blank list or matrix, or when you try to access or manipulate data it a position of a list or matrix that does not exist. (You can store data into the next open position of a… Read More

Press 2ND TEST (above MATH). The less than sign should be the fifth option.

First press 4. Then go to MATH and choose option 5, which looks kind of like *âˆš. Then type the number that would go under the radical. For example, to find the fourth root of 256, type 4*âˆš256.

After checking sites like Nexttag and Best Buy, they seem to run around $100, give or take.

You can find the Greatest Common Factor between two numbers by using the gcd function (which is found by pressing MATH and then choosing NUM and the top and scrolling down). For example, to find the GCF of 50 and 78, type: gcd(50,78)

One can find this answer by looking on eHow. A few other ways one can find this answer is to ask a math teacher or check out a book in the library on it.

Press MATH, choose NUM at the top, then choose round(. Type 0.9528, then a comma, then the number of digits you want to round to. For example, to round to three decimal places, type: round(0.9528,3)

To get to list 1, press STAT and then choose edit. If list 1 is not there, press STAT, choose SetUpEditor, and press ENTER. Then go back and press STAT and choose edit and you should see list 1. (This will set it up so that the list editor contains lists 1 thorough 6).

I suspect that you mean the function that is also called the floor function. The floor function of x, floor(x) is the maximum integer that does not exceed x. Instances: floor (-5.3) = -6 floor (-2) = -2 floor ( -1.3 ) = -2 floor ( 0 ) = 0 floor ( 1.5 ) = 1 floor ( 21.4 ) = 21 For a graph you might wish to see the wikipedia article.

To graph y2 = -3x, first solve for y. Doing this results in two solutions: y = âˆš(-3x) and y = -âˆš(-3x) Put the first solution into y1 and the second solution into y2. The two solutions together should form a sideways parabola.

Press MATH and select PRB at the top. The second option, nPr, is permutation. Example: To find P(8,3) type: 8 nPr 3

Press MATH and select PRB at the top. The third option, nCr, is combination. Example: To find C(10,4) type: 10 nCr 4

sin y is a function so the question does not appear to make any sense.

Here is an example of how to find the vertex of y=(x+1)2 + 2 by graphing. First enter (x+1)2 + 2 into Y1 and graph it (press Y=, enter the equation, and then press GRAPH). You should be able to see the vertex (if not press ZOOM, then ZStandard to reset back to the standard viewing window.) You need to know if the vertex is a minimum or a maximum. In this case, it is… Read More

Its in the bottom right corner, on the negative sign. to get to it, hit '2nd' in the top left corner, and then hit the negative, and then you'll get the Ans key.

Use >Frac to convert a number to a fraction. (Press MATH and >Frac will be the first option.) example: 5.5>Frac will result in 11/2 You can use Ans>Frac to convert you last calculation into a fraction.

To enter an arrow (pointing right, that is that only arrow there is), press the store key, which looks like STO>. The arrow is used to store data to variables (these variables are like boxes that hold information, not the kind that you solve for in algebra). For example, if you type 5->A, then A will now be equal to five.

yes, and usb cable that fits, will work.

This most likely means that a stat plot is on, and that a list that the stat plot was using is blank. (If you get a DIM MISMATCH error, it probably means that the lists that the stat plot was using don't have the same number of values.) If you are trying to graph the stat plot, go back and look at your data in the lists. If you are not trying to graph a… Read More

A program that you make (using the built-in TI-Basic language) will be saved when you close out of it. You will however lose it when you replace the batteries. One measure you can take to preserve your program is to change only two batteries at a time. This will normally prevent the program from being erased. Another thing you can do is archive the program. Press 2ND MEM (above +). Choose 2:Mem Mgmt/Del... and then… Read More

You have to make sure that your program runs smoothly. Make sure that the program does not get tangled up in too many Lbls and Gotos. Running several programs at once does not mean executing them all at once, but it simply running several segments at once. For those who know how to program a TI-83 or TI-84, you can try incorporating this program into yours. It is basically a number counter that will act… Read More

Hit the mode button, scroll down to the line that says, "MathPrint Classic." Once you have that line highlighted, hit the right arrow to highlight Classic, hit enter, and presto, no more MathPrint mode. Exit with Clear.

Yes; on the label containing the calculator it says it may be used on AP exams, SAT, ACT, etc.

In order to find the log with a power of ten, use the LOG button. For example, to find log105, type log(5). (The parenthesis after the g will appear when you press the LOG button. In order to find a log with a power other than ten, you will have to divide by the log10 of that power. For example, to find log82, type log(8)/log(2). In order to find the natural log of a number… Read More

You can use the cables that come with the calculator to get them from friends that already have them.

If you have an answer that you want to change into a fraction hit Math then 1 (labeled Frac) and then enter.

The easiest way to use a fraction on the TI-84 is to type it in like this: (1/2) for one half (3/4) for three fourths etc Use the division sign as the fraction bar, and put the whole fraction in parenthesis. Make sure you use the parenthesis, otherwise your answer will come out incorrect.

There isn't a sec key on the TI-83 Plus. Secant is 1/cosine, which is what is used to find secant on a TI-83 Plus. For example, to find the secant of 4, enter 1/sec(4).

From math class, some trigonometric identities: cot x = 1/tan x csc x = 1/sin x sec x = 1/cos x There are no built-in cot or csc formulas, so use the above. Remember that these give errors when tan x, sin x, or cos x are equal to 0.

Turn the calculator on and press 2nd, + (MEM), 2:Delete, 7:Prgm. This shows a list of all programs… Read More

The easiest way to learn how to use a new calculator is by trial and error. This calculator is very powerful if you know how to use it, but it can be confusing at times. (though much less so than the more powerful TI calculators. I digress) If you do not have time for trial and error though, you could find a user manual online at: http://www.education.ti.com/guidebooks/graphing/84p/TI84PlusGuidebook_Part2_EN.pdf And a helpful hint in general, if you… Read More

Click on "Y=" to begin graphing. In the upper left hand corner, there should be a tab that says "X=". Click the up arrow to move the cursor there. Click enter and you should be able to graph it from there! To see the graph, click on "graph". I hope this helps!

You can't really type fractions, but you can use the divide function to create the fraction line, and imitate it in a way.

Xmin is the lower limit to the graph that will be displayed. For example, if you graph something and set Xmin to 0, then the bottom of the graph will be where y = 0 (0 being the lowest x value o the graph). (The default for Xmin is -10, where the bottom of the graph is at the line y = -10.)

If you have a message along the lines of "Error, turn of calculator then turn back on," and can't seem to be able to download the software to update the calculator, this really helps. 1) Download IT Connect. 2) Go to the website below to find the newest version of software for your calculator. 3) DO NOT click download. Instead, right click on the link, and hit SAVE LINK AS. Save the link to your… Read More

dim mismatch occurs when you are trying to multiply matrices whose dimensions are imcompatible or when you are comparing two lists of unequal lenght.

Go to the y= button, and type in your equation by the y1 (if there's 2 equations, press enter and type the 2nd one in by the y2). Then press graph.

There is no simple answer because there is no known pattern to prime numbers. You could try dividing the each number by all the prime numbers less than or equal to its square root. If none of the go into the number then it is a prime.

Put the cursor on the first character of the line you want after the new entry line. Then Press 2ND INS, (above DEL), and then press ENTER.

There are online graphing calculators. However, as of writing, there is no emulated TI83 that runs within your browser. On the other hand, if you have a Ti83, it is possible to copy its ROM to run an emulated TI83 on your desktop via one of many emulators.

There is not cos2 button on a TI-83 plus. You will need to enter the cosine function and then square it. (Press the x2 button to get the squared function.) To type cos2(90) on a TI-83 plus, for example, type: cos(90)2

Press Window and scroll down to Xres. Change it to 2. Then press GRAPH. If the asymptotes still do not appear, increase the Xres number by one until they do. (It cannot go higher than eight.)

Short answer; you can't. But you can purchase (or borrow) a TI84 calculator and use the TI83's transfer cable to transfer data from the 83 to the 84 to your mac computer (the TI84 comes with a USB transfer cable).

Press "second" "math", and it should be the first thing listed. If you need other commands hit "second" "0" that will enter the catalog and you can press any letter (without hitting alpha) to jump to that letter in the list.

Put in your fraction (ex. 1/2+1/2)(use the divided by symbol for it) then add, subtract, or whatever. Then push the MATH button (underneath the ALPHA green button) hit enter then hit enter again and there is your answer. ex. 1/2+1/2>frac=1

The arrow keys are near the upper left corner of the keypad. If you want to type an arrow, use the store key. It looks like this: STO>.

You cant factor on the ti-84. however the ti-89 does do this but its almost easier to just do it in your head. Plus on the ti-89 the way you enter it in there is a very high risk for error.

Graph the two lines or equations you want to find the intersection of. Then adjust the window so that you can see the intersection point. (If you don't know where it is, try pressing ZOOM and choosing ZoomFit.) Then press 2ND CALC (above TRACE) and choose option 5, intersect.
