SOURCE: TI-83 Plus No Longer Squares Correctly

when you type -2 imagine your calculator doing the equation: -1 x 2. The - sign actually stands for a -1 so when you do -2 squared your calculator is simply following order of operations. It first squares the 2 making it 4, then it multiplies the negative making it -4. In order to get around this you must use parenthese. (-2)^2.

Hope this helped

SOURCE: What is wrong with my TI-89 calculator?

*oookhh ya thanku actually my exmaz r ova..so now i dont need it 2 practise but when some prob ill look at ur website..ok*

SOURCE: On my TI-30xs Texas Instruments, I cant figure out

Use the toggle button above the enter key. It looks like 2 arrows

SOURCE: My TI-89 will not calculate the square root of 3

Press the diamond key, then press ENTER to convert a symbolic result to a decimal result. If you want them all in decimal form, press MODE then F2. Scroll down to Exact/Approx and change that setting to Approximate.

Two ways:

2ND [square-root] ( 8 7 . 3 4 / 5 ) ENTER

8 7 . 3 4 / 5 ENTER then 2ND [square-root] 2ND ANS ENTER

The first sequence takes the square root of 87.34/5, the second sequence calculates 87.34/5 then takes the square root of the result.

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.

Hi there,

My name is adieh.have a great day.

I will give a simple example on how to convert your answer into decimal form. Indicated below:

Q: Simplify 1/2-5/13 convert to decimal

Answer:

Step 1: Enter 1/2 by pressing 1>a/b>2.

Step 2: Subtract by pressing - (negative sign or minus sign)

Step 3: Enter 5/13 by pressing 5>a/b>13.

Step 4: Find the difference by pressing**= (equals sign)**

**Step5: Convert to decimal by pressing (change)**

** You can find( change) on the right side of your calculator beside M+ key**

I am suggesting you to visit this website http://files.sharpusa.com/Downloads/ForHome/HomeOffice/Calculators/Manuals/Archive/cal_man_ELW535B_TeachersGuide.pdf

for you to have further knowledge about various functions of your sharp calculator since you are attending a business/algebra class.

Hope it helps.

Thank you for using fixya.

Your calculator is set to radians. To set it to degrees, press MODE, use the arrow keys to move to the "Angle" line, press right-arrow, press 2, then press ENTER.

The TI-30XA does not have to be switched to a statistics mode, the operations are available all the time. The choice of operations are somewhat limited; the calculator offers statistics functions for one dimensional data sets only (no linear interpolation of (x,y) value pairs, for example):

Example: calculate the average and standard deviation of the set { 3, 4, 5, 5, 5, 5, 6 }.

- [2nd] [CSR] - erase statistics data
- [] - add a number to the sample set
- [2nd] [] - remove a number from the sample set
- [2nd] [FRQ] - multiple entry of the same sample value
- [2nd] [n] - sample set size
- [2nd] [] - sum of all sample elements
- [2nd] [] - sum of the squares of all sample elements
- [2nd] [] - average of the sample set
- [2nd] [] - standard deviation (sample set is a complete set)
- [2nd] [] - standard deviation (sample set is a subset of a larger set)

Example: calculate the average and standard deviation of the set { 3, 4, 5, 5, 5, 5, 6 }.

- [2nd] [CSR] - erase stat memory
- 3 [] 4 [] 5 [2nd] [FRQ] 4 [] 6 [] - enter the data, note the use of [2nd] [FRQ] to enter the four occurrences of "5". Entering 5 [] four times would have done the same.
- [2nd] [] - display the average of the set, (4.714...)
- [2nd] [] - display the standard deviation of the set (0.8806...)

This shows you how to enter your data and calculate some statistical
values. Keep in mind that the variance is the square of the standard
deviation.

In the main menu select [STAT] icon to enter Stat mode and display the statistical data lists. Use the statistical data lists to input data and perform statistical calculations. Use the arrows to move the highlighting around the lists.

Example: Enter the following values in List 1

1st line enter 90 [EXE]

2nd line 85 [EXE]

3 79 [EXE]

4 75 [EXE]

5 70 [EXE]

6 68 [EXE]

7 56 [EXE]

When finished you press [F2:Calc], then [F1:1Var] and the statistical results appear on screen.

Title of screen : 1-Variable

x bar =74.7142857

Capital Sigma x= 523

Capita Sigma X squared = 39851

x lower case sigma n = 10.5249945

x lower case sigma n-1= 11.3682934

n = 7

Scroll down with Down arrow to access other data

minX =56

Q1=68

Med =75

Q3=85

Xbar -x lower case sigma n =64.1892911

x bar x lower case sigma n = 85.2392802

maxX=90

Mod=90

All you have to do now, is to look at the theory you learned and interpret what these values mean.

The truth of the matter is that there is no statistical mode per se. You just start entering data in a specific sequence.

If there is data in the statistics register (remnant of and old calculation) you must start by clearing old values :[2nd][CSR].

Here is a screen capture with an example that uses frequencies.

Hi,

You will have to report faithfully the message returned, you cannot use your interpretation of the message. Error messages are codified. Each one will correspond to very particular error conditions. I did check the manual for all possible error messages and there is none that states wrong info.

My hunch is that there are errors in your data, but I can't say what type of error: I do not have the actual message returned. Verify you data, item by item, and try again.

**To make sure that the calculator is well configured to do statistics**

Hope it helps.

Thank you for rating this solution

- Press [2nd][0] (CATALOG) and press [PRGM] (C) to jump to the first command starting with C.
- Scroll down to [ClrAllListsts] and press [ENTER]
- Calculator replies
**Done**

Click
on the Mode button twice until you see
“SD”. Select 1. This puts the calculator in Statistics Mode.
Enter the first number, 1.

Hit the M+. (n= 1 will appear in the window)

Enter the second number, 1.

Hit the M+ key. (n=2 will appear in the window)

. . . . .

Enter the last number, 7.

Hit the M+ key. (n=7 will appear in the window)

Hit shift, 2. (This invokes the S-Var option.)

Hit 1 for the sample mean. Hit Enter.

Hit 3 for the sample standard deviation that we will use in class. Hit Enter. here you can also ffind the sum of all numbers

Hello,

Here is how you enter it.

[+/-]0.693/8x4[2ndF][e^x][=] result is 0.7071588193 or as you wrote 0.7071

some calculators show an error message if you enter the [+/-] (the negative of a number before the number itself).

In that case enter 0.693 then press [+/-]. the calculator should put a small - sign before the 0.

You can try

0.693[+/-][x]4[/]8[2ndF][e^x][=]

Hope it clarifies things.
