You should feel happy that your calculator can perform some exact calculations. If you do not want the exact values you can press the SD key. You can also press SHIFT EXE rather than EXE alone.

Contrary to what you believe, results with square roots are exact. Decimals are approximate.

Press the SD key to convert from standard to decimal representation.

x^2 squares the value (multiplies by itself), x^-1 inverts it (divides it into one), x! calculates the factorial, and square root calculates the square root.

(Square root(7))*(Square root (15))=(Square root (7*15)=Square root(105)

Hi rayalak857,

Have a nice day.

Calculator does not have a solve program, but you can use it to solve the quadratic equation with a little effort. If you know the theory skip toward the end.

Here is the example:

Let aX^2+bX+C=0

1. First calculate the discriminant usually called Delta and given by

Delta =b^2 -4*a*c store the value in the variable D

If Delta is positive you have two roots X1 and X2 given by

X1=(-b+square root of Delta)/(2*a)

X2=(-b- square root of Delta)/(2*a)

If Delta is equal to 0, X1=X2=-b/(2*a)

If Delta i negative, no real solutions exist

You only solve if Delta is positive or equal to 0.

Putting in the values of a, b, and c

value of a (put you number) [SHIFT][STO] A

value of b (put your value) [SHIFT][STO] B

value of c (put you value) [SHIF][STO] C

[ALPHA] B [X^2] -4[x][ALPHA] A [x][ALPHA] C [=]

Value of delta is displayed. If it is positive, you store its square root in D

[Square root] [ANS] [SHIFT][STO] D ;

Calculate 1/(2*a) and store in variable F

1./(2[x] ALPHA A) [SHIFT][STO] F

To obtain X1

[ALPHA] F [x] ( (-) ALPHA B + ALPHA D ) [=]

To obtain X2

[ALPHA] F [x] ( (-) ALPHA B - ALPHA D ) [=]

Be careful: the (-) is the change sign not the regular minus sign.

Hope it helps. Goodluck

Thank you for using fixya.

To convert a single value to decimal, press Diamond then ENTER. To get them all that way, press MODE then F2. Scroll down to Exact/Approx and change it from Auto or Exact to Approximate.

Hello,

The question is not clear. What is the value of y?. The calculator cannot help if y is not known.**I will give you a few hints for this algebra problem:**

1. Taking the square root is equivalent to raising to the 1/2 power.

2. Power of a product is equal to the product of the powers. (X*Y)^a=(X^a) times (Y^a)

3. (X^a)^b =X^ (a*b)

Hope it helps.

The answer is Square root of 2. ( )

They way it works is :

sec theta at 45 degre is 1 over cosine of theta or

cosine of theta is square root of 2 over 2.

Therefore you have 1 over square root of 2 over 2.

After rationalization and simplification you should have .
