Asking the question twice is not going to help have a solution. What helps is clear information about what you were or are trying to do. As in the computer, certain menus are contextual: they are only available if the context (the action) is appropriate.

page, then press [f1] arrow down until format is highlighted and press [enter], this should open up a menu
with "axes........." as one of the options use the arrow keys to highlight the axis option and press [enter]
this will open up a menu to turn the axis "on" or "off", highlight "on" and press [enter]. Press [esc] to exit
the menu.

I cannot figure out how to solve factorials on my TI-83 Plus.

Enter the number whose factorial you want to calculate.
Press the [MATH] key under the [ALPHA]key.
Press the Right arrow 3 times to highlight the [PROB] menu.
Select option [4:!]
Press [ENTER

Note : Due to memory limitation, the argument of the factorial function must at most be equal to 69

How do I solve a polynomial equation: x^4+5x^3-3x^2-43x-60 on a TI-83 plus graphing calculator?


Sorry, but what you wrote is not an equation but a polynomial expression. You want to solve the equation x^4+5x^3-3x^2-43x-60 =0.

The solve( command, can only be used with real numbers.
The solve( is available through the CATALOG : [2nd][CATALOG], scroll down till you reach the command. Highlight it and press [ENTER]. The command echodes on main screen as solve( .
You complete the command by entering the expression (not the equation), the name of the variable you solve for, the initial guess , and { lower limit, upper limit} between curly brackets, and the closing parenthesis.
solve (x^4+5x^3-3x^2-43x-60 , x,0 {-5,0} ) [ENTER]
should give you the negative root,
solve (x^4+5x^3-3x^2-43x-60 , x,0 {0,5} ) [ENTER]
should give you the positive root.

It is implied that the expression is 0, so you should not insert =0, otherwise you get an error. Here for the lower limit is -5 you must use the change sign symbol (-) under the 3 key, not the regular MINUS.

You may ask how I knew that there were two roots when the equation is a quartic? By first graphing it to have an idea about where the roots lie and how many there are. You should always do that to speed up the search.

There is another way to zoom in on the roots: by drawing the graph and using the tools accessible under the [2nd][CALC] menu, namely the option [2:Zero]
The resolution of the TI83/84 is not good enough for this function that grows too fast, but I am inserting a picture of the curve from another calculator with a much better resolution.


Hope it helps.

Havent used my ti-inspire since last school year.wont turn on

Here is what the TI knowledge base says about a calculator failing to turn on

For the TI-Nspire™ Family:
  1. Remove thekeypad (for TI-Nspire) or the battery door (for TI-Nspire CAS) andremove at least 1 battery from each column of batteries. After 2-5seconds, reinsert the batteries and turn the unit on. This will causethe unit to reboot the operating system.
  2. Remove the keypad(for TI-Nspire) or the battery door (for TI-Nspire CAS) and remove atleast 1 battery from each column of batteries. After 2-5 seconds,reinsert the batteries and LEAVE THE UNIT OFF (do not turn on and thenback off). Hold down [Home] [Enter] [P], and while holdingthese keys, press [On]. The device will boot up as in the previousreset, but will display a menu with the following options. Please tryoptions 1, 2, 3, and 4 in that order. ** The [Home] key is located atthe top right of the TI-Nspire keypad and has a picture of a house onit.
Note:TI-Nspire family model options 2 and 4 above require that the OS be installed. The reset menu will only display if the unit is off and batteries have been removed/replaced as described above.

1. Cancel - The most non-intrusive reset option; no changes are made, the unit restarts.
2. Delete Operating System – The operating system will be deleted without deleting any documents.
3. Delete Document Folder Contents – This will delete the user’s documents, but will not delete the OS.
4. Complete Format – This will delete the OS and all documents for a total erase of memory.

Hope it helps you solve the problem.

"2nd" "ZOOM" (So, the "Format" menu)

Make sure CoordOn is highlighted as well as "AxesOn".

(These should be highlighted on this menu)

Just make sure all of the first options for that menu are highlighted, and your problem should be solved!
