Use the combination function. It's the shifted function of the divide key, marked nCr. For example, to find the number of combinations of 9 things taken 3 at a time, press 9 SHIFT divide 3 = and see 84.

True. The quotient of 28 and 4 is 7. The sum of 7 and 32 is 39.

never !

Divide by 100.

Critical value for what? In what context? Nuclear physics? Optics? Mathematics?

The Casio FX-570MS does not handle matrices. So you cannot create matrices, let alone invert them. Sorry. The Casio FX115 ES handles matrices for up to 3X3 dimension. Create the matrix.Have its name displayed on the command line and press the [x^-1] (reciprocal ) key.

Press SHIFT SETUP then select one of the Fix or Norm modes.

i am giving the key input with an example..
example-
at 0, value is 300
at 50, value is 270
so how much at 30...

On 991MS,
Go in Reg mode, for doing that : press Menu,Menu, 2

Enter the values as follows,

0,300 and press M+ key on the calci
(Note: there is a "," in between 0 and 300)

then enter the following,
50,270 and press M+ key

now enter the following input exactly as displayed below:

(30) shift 2 > > > 2 =


you will get the answer as 282.

I hope you got it!!!

LOFT!!!

Press SHIFT MODE 6 then select the desired number of digits after the decimal point. Alternatively, press SHIFT MODE 7 then select the desired number of significant digits.

buy a calculator just like your old 1 on ebay/amazon ='

When the angle unit is in radians sin^-1(0.184)=0.1850543940 radians When angle unit is in degrees sin^-1(0.185)=10.60283581 Your calculator is calculating the functions correctly) In the following screen captures the sine of the values is calculated with the unit specified inside the formula (degree symbol and radian symbol are inserted to show you the unit). In the last calculation the value of the sine is practically 0.184 Remember that when angle is in radians, for very small angles (less than 10 degrees), sin(x) and tan (x) are about equal to the value of the angle in radians

Sorry, but I see no vector, just a scalar value and nothing to solve for. If you want to calculate the value enter 3, press the power key (X^y, or Y^x, or ^, depending on the marking on the key, followed by the exponent to get the result 8.42587981071.

push the MODE button select 1:COMP should be back to normal after that

Antilog is a somewhat outdated terminology for the inverse function of the logarithm.

To calculate on your FX-115ES the base 2 antilog of 4, key in

Correct result is 16.

The SI unit for stress is N/m^2 (Newtons per square metre not Newtons per square millimetre) The figure above should be 23 .7389 * 10^ -9 or 0.0000000237389 N/m^2

Are you giving it a number between -1 and +1? Arcsine and Arccosine have non-real results for arguments have magnitudes larger than one.

The fx-115ES doesn't have any zoom capabilities. If you're asking about a Casio graphing calculator, which model?

Try resetting the calculator: [SHIFT] 9 (CLR). If the odd behavior is a consequence of hacking the calculator, then I have no idea of to reverse the process.
