There is no percent function. To enter 20, simply press "." then "2".

SOURCE: Change TI 84 OS to TI 89 OS??

And why, pray tell, would you do such a thing? You will ruin your Ti84 Plus Silver Edition and will not have a working TI89. Besides, TI connect will refuse to transfer it.
If you like the capabilities of the TI89 Titanium, buy a cheap or used one on e-bay or amazon.com and spare your TI84PLus SE.

SOURCE: Can you Factor on a TI-84? IF not, does the TI-89?

Well, to answer part of your question, yes... the TI-89 does factor like this. it is inputted like this:

factor(6*x^2+11*x+4,x)

Check the catalog in the TI-84 (which is 2nd-zero) and look under F for factor()

SOURCE: TI 84 won't graph more than one function

If you have used or just run the Transfrm Application, you will no longer be able to draw more than one graph.
To restore the native OS graphing capabilities Uninstall the Transfrm Application. Here is how to do it.

  1. Press the [APPS] key.
  2. Scroll Up to reach the bottom of the list faster.
  3. Point to Transfrm and press [ENTER].
  4. Select [1:Uninstall]
Note: Do not worry about Uninstall, it will merely kick the application from memory. Transfrm will still remain in calculator.

SOURCE: how do I use the intersect function on the TI-84

  1. You draw two or more graphs.
  2. After the graphs are displayed, press [2nd][TRACE] to access the (CALC)ulate menu.
  3. Select [5:Interesct]
  4. You will be prompted for a first curve: the equation of the curve will be displayed at the top left corner of the screen. If it is one the intersecting curves, press [ENTER]
  5. You will be prompted for the second curve. (You can move from one curve to another by pressing the UpArrow or DownArrow).
  6. After two curves are selected, you will be prompted for a guess for the X-value of an intersection point: you can use the keypad to enter a guess or use the left or right arrow to move the cursor towards a point of your choosing (if there are more than one point).
  7. After a short while the calculator gives you a solution.
  8. If it fails, you must make a better guess.

I encountered this same problem with the TI-84. Turns out you have to put your P (Percentage) as out of one hundred. For example. With my problem I had;

Trails: 13
P: 53/100
X Value: L1 (List 1)

And then it posted my probabilities to the L2 list. For some reason if you just put 53, or whatever your percentage of success in, it won't calculate.

Can not bring back the option to graph on the Y axis in the table mode of a TI-84 plus calculator. The entire column to input values into the Y axis of the table is deleted.


If the table has been created by entering a function in the Y= editor, then you can generate the table by just inserting the function again and pressing Table or Graph. If it is some (statistical) table you entered manually and where you chose the x and the corresponding y, then you will have to retype it again. Sorry

This seems like a silly question considering all that a TI-84 can do, however is there a percent "key"?


No, there isn't. You can always convert a decimal value to a percentage by multiplying by 100.

Likewise, there is no permil key or ppm (parts per million) key.

How do input subscripts into a program with a TI-84 Plus? Like Y(sub 1)=y


Use the square brackets ("[" and "]"). They're the shifted functions of the multiply and subtract keys. For Y(sub 1) enter it as "Y[1]".

How do you use a plus or minus sign on a TI-84


Hi,
You cannot use the ± in the definition of a function. If you need to consider two alternatives, you have draw each function separately, one function as Y1 and the other as Y2. I just checked the catalog of commands, and there is no ±.

Hope it helps.
Thanks for using FixYa
