You may be making a confusion between intercepts and intersections. Intercepts are crossing of the axes. Intersections are between two curves: You need to have two curves graphed. You choose the first curve by selecting it (Up or Down Key), and then the second one.

Read about the nature of the cursor. It can be on Insert or overwrite. If the cursor is full square and flashing, that mean the memory register for the input line is full and you cannot input anymore strokes.

If either error occurs when trying to graph a function (not a STAT PLOT), the error can be corrected by turning off the STAT PLOTS. The following steps will turn the STAT PLOTS off, allowing the graph of the function to be displayed.• Press [2nd] [Y=] to access the STAT PLOTS menu. • Select 4: PlotsOff. • Press [ENTER]. • Try graphing a function like y = x^4-3x^3+6x-1

Use the division key.

Factor both the numerator and denominator, and then divide both the numerator and denominator by the greatest common factor. For example, 1/3 + 1/6 = 2/6 + 1/6 = 3/6. We have to simplify 3/6. The factors of 3 are 3 and 1. The factors of 6 and 1, 2, 3, and 6. The greatest common factor is 3. Dividing the numerator and denominator by 3 results in 1/2. Good luck. Paul

How about providing the question that your trying to solve and we will work out why your are getting an error. Good luck. Paul

Maybe you need to upgrade the operating system? Updating the TI84 Operating System How to update upgrade the OS on TI 84 and enable MathPrint TI 84 Plus Calculator Google Search How to Upgrade the Operating System on the Graphing Calculator

DOMAIN ERROR: - You specified an argument to a function or instruction outside the valid range. This error is not returned during graphing. The TI-84 Plus allows for undefined values on a graph. - You attempted a logarithmic or power regression with a LX or an exponential or power regression with a LY. - You attempted to compute GPrn( or GInt( with pmt2 < pmt1.

There is no problem, see captured image below:

Here are some possible reasons for the error ERR:STAT

enter upper number divided by lower number.

Help lost my L1 or L2 on the Ti graphing calculator

The screen is probably leaking the liquid crystal.

Your right you should be in degree mode. However, my guess is you are somehow entering in cot wrong in your calc. Recall cot = 1/tan! In your graphing calculator enter: 35(1/tan(61) = 19.4. Hope this helped!

INVALID DIM error message may occur if you are trying to graph a function that does not involve the stat plot features. The error can be corrected by turning off the stat plots. To turn the stat plots off, press 2nd (stat plot) ,and then select 4:PlotsOff. • You specified a list dimension as something other than an integer between 1 and 999. • You specified a matrix dimension as something other than an integer between 1 and 99. • You attempted to invert a matrix that is not square.

See captured image below. You have to use (-) sign

the only thing that I can recommend it to stick it in a zip-lock bag full of dry rice for 24hrs. Sometimes there is moisture that you just can't see & rice has a way of attracting liquids from electronic components. Hence, potentially saving your electronic device. If this does work -- if I were you I would suggest always storing your calculator, ritually, in a zip-lock bag so this does not occur again (I do this -- TI-84s are not cheap accessories -- better safe then sorry). Good luck!
