Question about Texas Instruments TI-83 Plus Calculator

Ad

Have you tried changing the batteries? I'd try that first thing. From your description, the problem sounds like you have low batteries. The RAM shouldn't clear itself when you turn the calculator on unless you tried to turn it on when the calculator didn't have any juice. The TI-83 has four AAA batteries and one CR1616 battery it uses for memory backup. The CR1616 isn't enough to power the calculator, just enough to keep your calculator from losing its RAM contents while the primary batteries are out. If you try to power the calculator on without primary batteries, the backup fails. However, the TI-8x line is usually pretty good about warning you when the batteries are low by displaying a big warning message when you turn it on about the batteries being low and a recommended change of batteries. It might not, though, so you really can't be sure until you try a fresh set of batteries. Good luck!

I get the same answer. Is b wrong? When I do it in Excel I get b= -2E+06, which is -1 797 322.99 rounded to the millions, in scientific notation.

Let me know if you have any questions.

Good luck,

Paul

You can't simply enter 7x+9=30 into the calculator, there is a way to calculate what the x is but its been a few years since I've done these..

Hi,

Listen! I am no seer, but I suspect that the batteries in your calculator are depleted. Replace all of them because the backup battery is not able to keep the flash memory refreshed.

Hope it helps.

Parabolas are forms of the base equation X^2. So press the [Y=] key, and then type in the variation of x squared that you want

to do logarithms with other bases, use change-of-base.
let's say you want to do log base 5 of 25. for clarity i'll write this as log(5) 25.
you would have to do log(10) 25 / log(10) 5 to get 2.
key sequence:
[LOG], 2, 5, ), / (divide), [LOG], 5, )

Yes you can use it, here is the formula: Y= V(t+ (i/c))^(tc) V=amount put in, t=time, i=intrest rate, c= amount of times it is compounded.

(I know this because I have a TI-83 calculator)

The tables will not say Y specifically, they only say L1, L2, L3, etc. UNLESS you type in an equation in the "Y=" button menu. When you type an equation in on that page, and then hit "2nd" "GRAPH", you will get X and Y values for that equation.

The TI 83, 84 seris can not store more than 10 equations. the TI 86 and above can have infinate, but not the 83, 84s. If you have catalog help in your apps, you can run that, and it will be able to tell you all the syntax of every function it has.
