Question about Casio FX-115ES Scientific Calculator

# Hi there. I'm using Casio FX-570ES scientific calculator. I would be glad if you could guide me as to how to obtain derivative of a polynomial expression e.g. y=12(x^2+6)^5

The syntax of the command is

where function is the expression you are differentiating
x is the value of variable x at which you are evaluating the derivative, and tol is the tolerance (the error) you are willing to tolerate in the result.

If you do not want to specify a tolerance just omit the last comma and tol.

To enter the command d/dx you use key sequence [SHIFT][Integral]
To enter the symbol x in the expression you press [ALPHA][ ) ]
To enter a comma you use [SHIFT] [ ) ]
To enter a power of 10 in the tolerance use [x10^X] key

Example : Calculate

The key sequence is as follows
[SHIFT] [Integral] 3 [ALPHA] [ ) ] [X^2] [-] 5 [ALPHA] [ ) ] +2 [SHIFT] [ ) ] 2 [SHIFT] [ ) ] 1 [x10^X] [(-)] 12 ) [=]

DO NOT confuse [SHIFT] [ ) ] which enters the comma and [ALPHA] [ ) ] which enters the varHi there. I'm using Casio FX-570ES - k24674_76.jpg>

I'm using Casio FX-570ES scientific calculator.
I would be glad if you could guide me as to how to know the Factor Theorem using calculator.eg.P(X)=X3(cube)-6X=5. How to know the X value, and then the substitute the value X, the equation become 0.

### Hi,how can I calculate median using fx-570es plus?

The median is the number is the middle.

Using the calculator, you can follow the Statistical Calculations (Stat) on pages 22 and 23 of the attached manual. http://support.casio.com/pdf/004/fx-570_991ES_PLUS_E.pdf

However, it might be quicker to just put the numbers is order from lowest to highest and pick out the number in the middle.

For example, take the numbers 3, 5, 4, 7, 6, 4, 9.

Putting them in order, we get 3, 4, 4, 5, 6, 7, 9

There are 7 numbers so we want the 4th number (3 numbers to the right and 3 numbers to the left). In this case, the 4th number is 5 and that is our median, as half the numbers are lower than it and half the numbers are higher than it. It the number of numbers is even, you take the average of the two middle numbers.

Good luck,

Paul

### How to solve y3-113y2+350=0

You can try to factor the polynomial. If not you can find approximate roots graphically: You draw the function y=x^3-113x^2+350 then examine the graph to locate the zeros, i.e the values of x where the function is equal to zero.

### How do you find the derivative without values for x

I am not sure I understand what you want, but if I am guessing right, you need to calculate formulas for derivatives, where the name of some variable appears eg= d(x^2)/dx = 2 x.
Sorry, the calculator does not have a CAS, you cannot perform symbolic calculations regardless of the subject (derivatives, integrals, sums of series, factoring polynomials, expanding polynomial products, polynomial division, etc.)

### I'm using fx-570ES..i couldn't find the inverse matrix using the method shown..it keep showing syntax error..hope u can help me..

Not all matrices are invertible. The matrice must be square.The matrix must be non-singular: Its determinant must be different from 0. Your error comes probably from the key you used to calculate the inverse. Use the reciprocal key, the one marked with x^-1. If the marking is not ON the key, use the SHIFT button prior to pressing the relevant key.

### Does anyone know how to calculate derivatives using the casio fx-115es? For example: find the derivative of f(x)= 3x^3=3x. Thank you!

hello,
The calculator will calculate the derivative at a point. It will not give you the formula for the derivative, just the derivative at the point you choose.
Sorry, it can ONLY do NUMERICAL differentiations and integrations.
