Calculators

The Einstein Calculator is a calculator made by Albert Einstein. I have no clue what its about. Probably a normal calculator. I see u chase d! Desiree s. :)

Texas Instruments graphing calculators are really easy to use and there are a lot of applications and programs available for the TI graphing calculator platforms (TI-83+ family, TI-84+, TI-Nspire, and TI-89 family). Thus, you will be able to easily find a program for your specific class (Calculus, physics, chemistry, etc.) at Texas Instruments app store and also open source program repositories like ticalc.org.

The TI calculators also are the most commonly used in the more advanced mathematics courses, including Calculus I,II,III, differential equations, etc. because they have all of the features and functions one would need in a easy to use, user-friendly interface.

* Also, if you are interested, you can download a software package for your TI graphing calculator to help you improve your score on the SAT test at www.calc-tech.com . It's called the SAT Operating System (SAT_OS) and can be used during the actual test to reduce time on math problems and improve the accuracy of your calculations.

Assuming you have a scientific calculator which has a square root button ([√]) the method depends upon which calculator you have, and in what mode the calculator is set.

The most recent Casio calculators have two modes of entry: MathIO and LineIO. InMathIO the sequence is:

[√] [<expression>] [=]

In LineIO, if the <expression> is more than one number brackets needs to be entered:

[√] [(] [<expression>] [)] [=]

This LineIO type of entry is used on the older Casio calculators. With older models of Casio calculators, and other manufacturers the functions work on the displayed value which is replaced by the value if the function. With these calculators, the expression is entered first and then the square root key is pressed:

[(] [<expression> [)] [√]

parentheses are only needed if the square root is of an expression.

Examples:

Square root of 16

MathIO: [√] [1] [6] [=]

LineIO: [√] [1] [6] [=]

Other: [1] [6] [√]

Using Pythagoras to find the hypotenuse of a right angle triangle with sides 3 and 4:

MathIO: [√] [3] [x²] [+] [4] [x²] [=]

LineIO: [√] [(] [3] [x²] [+] [4] [x²] [)] [=]

Other:[(] [3] [x²] [+] [4] [x²] [)] [√]

With MathIO the square root symbol extends over the expression as each key is pressed which is why the parentheses are not needed in the last example.

You can type letters from A-F, X, Y and M by pressing alpha.

That topic is covered, exhaustively, in detail, with examples,

in the instruction booklet that comes with each of the many

different models of scientific calculator .

Youy can use a TI 84.

The square root of 55 will be roughly halfway between 7 and 8.

7.5 is too high.

7.4162 works for me.

This is for a Statistics class and I need help on how to operate step by step this calculator.

Use this to help you out:

Just ctrl+f what stats function you want, for example variable (when doing variable testing).

because before calculater we used abacus.In abacus we learnt in reverse order

You type the number in then percent it by the number you want

I would say centimeters, not inches

To find the Volume: (1) find the flat area (A = Pi*R²), (2) multiply the Area by the Depth/Height (V = AD). To find how much water the vessel will hold: water = 231 cu inches per gallon, or 7.481 gal per cu ft.

You seem to be unaware of the fact that you can obtain the answer easily by using the scientific calculator that comes as part of your computer. In general the nth root is extremely difficult to find.

Yes, a calculator is a very simple computer. Since Personal Computers use faster processors, they can calculate faster.

This can be transalted into other VB scripts as the code is quite simple and easy to follow however i have put headings for each section as a guide to it's function

First, create your list of numbers by typing: {1,2,3,4,5,6,7,8,9,10} hit 'STO>' button, which means "store as"

then name your list, something like 'L1'

and HIT ENTER to store

Now, hit STAT / CALC / 1-VAR STATS <Enter List name>...

and then scroll down until you see:

n = 10

minX = 1

Q1= 3

Med= 5.5

Q3= 8

maxX= 10

It is used to make numerical calculations.

Yes, you can process it on a TI-83 or higher, your calculator can compute it for you. To do it your problem must include a list of data points. To enter the data on your calculator, push STAT. Then go to EDIT. In edit there is a chart. The top row says L1, L2, etc. If there are already values in your lists, you can clear them by going up and highlighting L1, press clear, and then the down arrow. That will clear the list. To enter data, move to the rectangular box under L1. Type in your first value and press enter. Continue to do so until all values are entered under list one. Next, press STAT. Move over to CALC and select 1-Var Stats. Press enter. A buch of data will pop up. The symbol on your calculator for standard deviation is Sx, and there will be a value listed. That is the standard deviation for your data set. Some other things that are good to know with the info we have produced: _ X = mean/average of data n = number of data points minX = minimum x value Q1= quartile 1 Med = median Q3 = quartile 3 maxX = maximum x value Sx = Standard Deviation And a Q looking thing and a X is (Population Standard deviation) "Qx"

Before calculators, trig functions in general were evaluated using a slide rule (fast, but accurate to only 2-3 significant digits, and interpolation tables, which required interpolating between values in a printed table of function values to get up to 3-4 significant digits. Tricks were a big part of the repertoire - for example for small angles of less than about 7 degrees, sin and tangent are equal to the angle in radians.

Spherical geometry was fairly labor intensive, to say the least, since several trig functions are used for even simple distance and angle calculations. Special tables were printed for common cases, such as plotting great circle distances and bearings for terrestrial navigation.

In a desert island setting, given infinite time and desire, trig functions can be calculated using various converging series, with the Taylor series being a commonly taught (though slow!) example.

The disadvantages of calculators is that they are no longer practical or convenient. Unless scientific in nature, most people use the calculators on their smart phones and wireless devices. While stand alone calculators are still in use, their popularity has immensely decreased across the nation.

you can got to www.go.hrw.com so you can caculate your mathmatics promblem.

I don't know an exact year, but handheld calculators first appeared about 1973.

Desktops were several years earlier.
