Question about Texas Instruments TI-83 Plus Calculator

I changed the batteries in my TI 83 and when I went to turn it on, the entire screen was black. I tried leaving them out for a few hours, doing a few different resets, and now, since I replaced the back up battery too, it doesn't show any signs of life when I turn it on. I know the batteries work since I plugged them into another TI 83 (great, I have two and neither works!) but I can't get any life out of this one. Any help would be fabulous!

I was having the same problem...I found the info below on another blog and it helped me fix my calculator problem. Take out all the batteries, hold the DEL button and put the batteries back in (keep holding the DEL button until all batteries are put back in). This will restart the calculator and restore it to its default settings...but it makes it work again!

"Reflashing the OS is probably the thing to do
now. I think there's some trick that throws the calc into OS receiving
mode. Hold down DEL while putting the batteries in? I don't remember if
that's it. Go to 1-800-TI-CARES/ti-cares@ti.com if you need specifics
on getting the calc to take an OS upload given the state it's in."

With power disconnected, remove all shredded residue from mechanism.

118.3 cu3 = 24.0985 cu2 (square feet) 24.0985 X 12inches = 289.182 square inches.

It might be 118.3 cu3 X 12 inches = 1419.6 cubic inches

Not quite sure what you needed.

Use the words: decimal part, not decimal fractin

**Any number whose decimal part is periodic (has a recurring pattern that repeats indefinitely) is equivalent to a rational number, IS a rational number**

0.345 345 345 ... =345/999=115/333

In the following screen captures, discard the last digit if it does not belong to a period. It is the effect of rounding up of the calculator

**Period is 345**

**Period is 1**

Period is**09**

Period is** 79**

In general, if you have a decimal part of the form 0.d_1 d_2 d_3....d_n d_1 d_2 d_3 ...d_n ... where d_1 is the first digit of the period, d_2 is the 2nd digit of the period, ..., d_n is the n-th digit (and the last one) of the period, then the fraction representation of

0.**d_1d_2...d_n** d_1d_2... d_n ...=(**d_1d_2...d_n**)/(99...9) where the number of 9's in the denominator is equal to the number of digits in the period.

Once the fraction is found, one should reduce it to its simplest form.

0.345 345 345 ... =345/999=115/333

first of all change or re-install the scanner's driver

The circumference of a circle is C=2 * pi * r or C= pi * d.

What do we know? C=47.1 and pi.

What are we trying to calculate? d

Put what we know in the equation and solve for d.

47.1 = pi * d

To isolate d, we have to divide both sides by pi.

47.1

------ = d

pi

I get 14.99' or approximately 15' as the diameter.

Good luck,

Paul
