Question about Texas Instruments TI-86 Calculator

This should be a simple slope graph, but my calc.(TI-86) won't graph it.

Error 07 Syntax

Means you made a typing error while entering the equation. Using the minus sign instead of the negation sign (change sign) (-), can produce a syntax error. Maybe you need to explicitly type the multiplication sign

y= (-) 1.5*x +3

Try entering it as 3 - 1.5*x

Hi there,

Save hours of searching online or wasting money on unnecessary repairs by talking to a 6YA Expert who can help you resolve this issue over the phone in a minute or two.

SOURCE: error :invalid DIM

This is my first post on this site, but I've had friends at school ask me about this. Apparently I'm like a calculator genius or something...

One solution I know of is clearing the RAM. Sounds strange, doesn't it? But it fixed three different calcs.

Be sure to back up or archive important data before doing this.

SOURCE: Graph feature is not working on TI-83

you have one of your stat plots on that is what is messing it up. So either turn off the stat plots. Or just reset your calculator. hit 2nd then the plus (+) key then 7 then 1 then 2. Good luck

go to:

mode

select DEGREE rather than RADIAN three lines down.

SOURCE: MATH Graph Style Icons

go to apps menu, go to transform app. click uninstall and go to y= screnn and should be a slash on the left and you should be able to graph more than one equation.

SOURCE: Ti-89 gives error of "Undefined Variable"

You have to reset

• Press [2nd] [6] (MEM) [F1] [ENTER(RAM)]

• Select 1:ALL RAM

• Press [ENTER]

• Press [ENTER]

NOTE- erased half of my programs(I think only the ones in the main directory)

Read on how to set up calculator for graphing. And check your input.

You do not say if you get any error message.

Try to reset the calculator Press [2nd][+] to open memory management.

Press [7][RESET] followed by [1:All RAM] [2:Reset]

Then open the Y= editor and to the right of Y1= type in [X,T,theta,n] and press [ENTER]. You will see the straight line y=x.

Please report back what you get.

To clean the slate so to speak, just reset the RAM.

Calc

- Press [2nd][+] to access the (MEM)ory management function
- Press [7:Reset]
- Press [1:All Ram]
- Press [2:Reset]
- Press [CLEAR] to erase the "RAM cleared" Message

To restore memory on a TI 84 to factory settings follow the directions on pages 108 and 109 of the instructions manual (TI 84 Plus Silver). Otherwise look in the index for RESET MEMORY to get the right page. Be sure you read the precaustions!!!!!!

maybe try changing the small memory battery inside, I think its a cr1616 or cr1620. If this doesn't work use it as a paperweight.

This is simple... Back up all RAM, (press second+, then 2, then 1, press enter to back up something if backed up it will have a star by it) Then clear your RAM (pull out your batteries while the calc is still on or press second+, then 7, then 1)

Hope this helps!

Hope this helps!

You are probably entering the equation wrong. Dont do this: 3600=x(2+2) You have to enter the equation 3600=x*(2+2)
