To graph inequalities (y is 'less than', 'greater than', 'less than or equal to', or 'greater than or equal to'), turn on the Inequality Graphing app. Do to this, press APPS and choose Inequalz.

You should see the 'less than', 'greater than', 'less than or equal to', or 'greater than or equal to' symbols at the bottom of the Y= screen. To change and equals sign to one of those symbols, highlight the equals sign, press ALPHA, and then press the button directly under the sign you want to use (ALPHA TRACE for greater than, for example).

To turn of Inequality Graphing, press APPS, choose Inequalz, and then choose Quit Inequal.

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).

Well, ti83s don't have archive memory(ti83 plus does though) while ti84 has archive. Ti84s allow you to start a two digit label with a letter, while ti83 doesn't, which is why there is an ERR:VERSION when you try to transfer programs with labels like A4 from ti84 to ti83. Also, ti84s default connection cord is different from that of them ti83, and ti84 uses a mini-USB as ti83 uses a different one, the one labeled 'I/O' on the ti84.

On my graphing calculator, a TI84 Plus, I can enter the equation into the Y= (a button) and then graph it by hitting the Graph button.

Either press the carat button followed by a 3 or go to the math function and select cubed.

No. I believe TI83+ and TI84 do use an operating system.

Press your Y = button, press X, press second button and then catalog. Press up button to save time and scroll up to > and press enter. then 4. This, >, symbol may be someplace else, but I do not renumber where and all symbols are in the catalog.

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

Go to Texas Instrument's homepage and search for the manual. It kind of has its own confusing programming language. In other words, it's not simple.

I believe that that isn't possible unless you have it ported to ti84 or you know how to. the file format is different, and the game is built for a separate calc.

The TI-85 was the second graphing calculator made by Texas Instruments. (The first was the TI-81). The TI-84 is a much newer version and has more functionality and memory. The only real advantage that the TI-85 has over the TI-84 is that it costs less. As far as where you are allowed to use the calculator, almost every test or class that allows a TI-85 will allow a TI-84 as well. The TI-84 is a much better investment. (If the TI-84 is too expensive, look into getting a TI-83. This model is also newer than the TI-85.)

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. Use the up and down arrows to select the first equation you want to find the intersection point on, and press ENTER. Do the same thing for the second equation. The calculator will now say "Guess?". Use the left and right arrows to move the x-like shape as close to the intersection point as possible, then press ENTER. The calculator will tell you the intersection point and the bottom of the screen. If you get a NO SIGN CHNG error, then it might be because the intersection point is not on the screen. Change the window so that you can see the intersection point and try again. Also, make sure that your guess is somewhat close to the intersection point.

Press 2ND and then MEM, (above +). Choose the seventh option, Reset.... In order to reset settings and not clear memory, choose the second option, Defaults.... Then choose the second option, Reset.

TI84 calculators can be purchased at retail stores such as Best Buy, Future Shop, Staples and Office Depot. Prices range at approximately $140 and can differ by retailer.

One can purchase a TI 84 Plus Silver Edition from the following shops: Amazon, Calculators Direct, eBay, Walmart, Target, eBuyer, Staples, Best Buy, to name a few.

Press 2ND MATRIX (above x-1). Select EDIT at the top with the arrow keys. The select matrix [B] and press ENTER. You can now edit the matrix. (Use the numbers at the upper right to set the size.)

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)

This is probably because one of your stat plots is trying to use two lists that aren't the same length. If you are not using stat plots, then press Y= and deselect all the plots at the top. (For example, to deselect Plot1, press the up arrow key until it is highlighted and then press ENTER.) If you are using stats plots, check to make sure that the lists being used are the same length and that they have at least one item in them. (You can see what lists are being used and set what lists are being used by pressing 2ND STAT PLOT [above Y=]. You can edit lists by pressing STAT and then selecting Edit...) The invalid dimension error can also happen if you try to invert a matrix that is not a square matrix, (for example, a matrix with dimensions 2 x 3). Matrices can only be invented if they are square (for example, a matrix with dimensions 3 x 3).
