To convert kilometers to miles on a TI-84 calculator, you can use the conversion factor: 1 kilometer is approximately equal to 0.62137119 miles. You can multiply the number of kilometers by this conversion factor to get the equivalent distance in miles. For example, to convert 10 kilometers to miles, you would do 10 km * 0.62137119 miles/km = 6.2137119 miles.
No. I believe TI83+ and TI84 do use an operating system.
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).
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.
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.
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.)
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.
-4
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).
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.)
