Fractions how to in put them

SOURCE: fractions

there is a A b/c button. This is the button use to enter fractions. so 4/3 would be entered as 4 |A b/c| 3

If you want to have the answers in fractions as well, then I believe you hit more a few times. And then there should be a display option, in the display option, there should be a b/c. This will show your answers in fractions. Hope it helps

SOURCE: Can I factor a polynomial

The short story is that this calculator does have a computer algebra system or CAS and thus cannot factor polynomials with arbitrary (unknown) coefficients or known coefficients.
However if the coefficients are given you can ,if you are willing to travel that way, factor approximately a polynomial P(x).
Basically, the idea is that any polynomial P(X) of degree n can be written in the factored form (X-x_1)(X-x_2)...(X-x_n), where x_1, x_2, x_3,...x_n are the roots (real or complex) of the equation P(X)=0.


The procedure ( for a 3rd degree polynomial) is as follows: (the fixYa site parser will remove the plus signs, so I am writing the whole word plus instead of the mathematical sign
If you want to factor a cubic polynomial P3(X) = aX^3 plus bX^2 plus cX plus d , you write the corresponding cubic equation as aX^3 plus bX^2 plus cX plus d =0 , then you divide all terms of the equation by a to obtain

X^3 plus (b/a)X^2 plus (c/a)X plus (d/a)=0.

You use the calculator to solve (approximately) this equation.
Suppose you find the 3 roots X1,X2,and X3. Then the polynomial X^3 plus (b/a)X^2 plus (c/a)X plus (d/a) can be cast in the factored form (X-X1)(X-X2)(X-X3) and the original polynomial P3(X) can be written as

P3(X) = a*(X-X1)(X-X2)(X-X3)

You can handle the quadratic polynomial the same way.
P2(X) =a*(X-X1)(X-X2) where X1, X2 are the two real roots.

To find the various roots you must use the solve( application.

SOURCE: I have a Casio fx-9750GII,

From the Run Mode (select it and press exe), enter Setup (Shift Menu) and then highlight Angle. Press the function key that correponds to Deg and then press Exit.

The manual for the Casio Fx-9750GII is here: http://support.casio.com/manualfile.php?rgn=1&cid=004002013 . Other calculator manuals are here: http://support.casio.com/manuallist.php?rgn=1&cid=004 .

I hope this helps.

If it is possible, you convert a displayed decimal result to a fraction by pressing the key marked [F-D]. It is to the right of the [a b/c] key.
