Calculator TI 84 plus calculator

[saunders is god]

Guys, don't know if anyone else has this problem but on my TI-84 plus I can't scroll up to see past calculations. IS there anyway to fix this annoying problem?

I think that I had this problem long time ago, but, unfortunately, I don't know how to fix it.

I'd suggest asking your math teacher actually. Our HL math teacher seems to be a complete genius with his calculators...

come on guys, there has to be more than two other people out there with this stupid problem???

Ask your teacher, as Drake Glau said.

If your teacher doesn't know how to fix it, contact the TI calculators product support.

I dont think it can, I have this problem like every day. You could try pressing alpha up, but theres really not much you can do about it.

This is a design flaw in both the TI 83 and 84

You can press 2nd + Enter to go up one line in your history. Keep pressing 2nd + enter to go further back.

There's also a way to use the arrow keys to navigate, but this is a simpler solution if you don't want to update your software.

Anyone know how to deter the calculator from rounding off to 1 when working out probabilities. The probability would have been very large 0.999999221231 or something, but is there any way to make sure the calculator won't round off?

Stuffed me up in a mock.....

edit: nevermind I was using the calculator wrong....

Can anyone explain how to plot x against y on a calculator to get quadratic equation ? I mean literally step by step starting from turning IT-84 on. I only know how to draw a function when I know the equation, but I only have x and y and I need to find quadratic equation.

I enter CALC-QaudRegression and then I stuck because there is nothing on the screen. I know that the screen must be with x and y and I don't seem to find how to get there.
