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.

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.

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

• 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.

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 do the operation to get a decimal number.

Isolate the integer part (to the left of the decimal point)

Convert the non integer part (decimal part) into a fraction.

Write the result as (integer part) (fraction part)

3/2=1.5

Integer part is 1, decimal part is 0.5

0.5 as a fraction is 1/2

3/2= 1 1/2

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!

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!

If you only cleared RAM, a program that was loaded no longer resides in RAM, but if it was archived, it should still be available.

If you cleared all Including Archives, then it is lost.
