Could you just enter 6.0221415 × 10^23? This is within ± 0.0000010 of the actual number. Good luck. Paul An Exact Value for Avogadro Number

Solve for x, do not try to graph it using the TI 83 Plus. It only graphs functions not equations.

Does not exist on TI8x Family.

You can do that only if the decimal part (the part after the decimal point) is exactly 0. Anything else will be a rational number { a fraction with integer numerator and denominator}

Invalid dimension is displayed if the two columns have unequal length (number of elements). Try plotting the scatter plot first, then worry with the Zoom.

If you fill all the entry line memory, the calculator stops responding. Clear entries to free memory.

make sure that there is nothing sticky in your calculator. It's likely that you got something sticky in there and now the pin that you would push down when you push the key is permently down. So if you can kinda try to make it not stick then your set. If it's a teqnical problem then it's time to buy a new calculator. I just went and bought a ti 84 silver and it's great. Best of luck

It is a frequency table where the entries are the relative frequencies relative frequency= (frequency/sum of all frequencies). The frequency can be expressed as a decimal number or a percentage. In that last case, the total of all frequencies will be approximately 100% (due to rounding errors).

Connect it to a computer with TI Connect installed. Run TI connect and open the Updates TAB. Update OS. Of course you must be connected to the Internet. Or use an IO cable to connect it to a similar calculator and send the OS from the 2nd machine to yours. Read about the procedure in the Manual.

Sometimes these is corrosion on the contacts from the corroded batteries. Try cleaning it off with some sandpaper. Make sure to thoroughly wash your hands after or use gloves! Good luck.

Your question is not clear at all. What are all those area measures in cm^2? Take two segments that correspond to one another and for which you have the lengths. This will allow you to find the scale factor k. k= (length of a segment in smaller figure)/(length of the corresponding segment in larger figure). Then Area of smaller figure =k^2(area of larger figure) In the formula above insert the area of the larger figure as given to you or as calculated by you using the shape and dimensions of the figure.

Hello,
Check this article. It will show you how to force the reinstallation of the OS. If that does not solve your problem, you may have to send calculator for service.

Hope it helps.

Hi,
Not every function on the TI83Plus calculator has a dedicated key, or is accessible through a key sequence. Among the keyless function is the factorial function.

To access the factorial function

1. Through the catalog of commands: press [2nd][0] (CATALOG) and scroll Up till you reach the exclamation mark !
2. Press [MATH]. Use right arrow to highlight PRB menu. The factorial function is the 4th in the list.

Syntax

Type the number and use one of the foregoing access methods to echo the exclamation mark on the home screen and press ENTER.
Ex: 12! =479001600

The largest number that you can use with the factorial is 69.

Hope it helps.

Be careful with the order of operations. Try (ln(55)-1)/2You can never have to many parenthesis. remberr PEMDAS ln is an exponent so you want to put it inside parenthesis in oder to follow the Order of operations.

Make sure Z and Y are not defined as a variable in the flash memory, use the command to CLRVAR: Z,Y in your program.

Check your Memory if you have to many applications or variables it can take memory away processing power, delete the stuff you don't need.

Use three parts 24% nitrogen, and one part 12% nitrogen.

hi just type 3.5 / 5 press the enter or equals key to get .7 for a result, if you like the answer in fractions it 7/10 hope this helps.

Sorry to disappoint you, but there is no such button or command on the TI8x family of calculators.
To convert from decimal ratio to percent value, move the decimal mark two places to the right.
To convert from percent to decimal value, move decimal mark two places to the left.
