Hi I have a problem with my Casio FX 1.0. It only shows a square black box and an arrow in the rigth down-corner. I can move the black-box, but I can't press anything! Well.. I can press it, but nothing happens :)

Hope there is a simple way to fix this... Hope its just me that doesn't know my friend the Casio well enough.

The calculator belongs to a new generation of scientific calculators that enjoy the feature called MathPrint by TI, Natural Display by Casio, and WriteView by Sharp

When the calculator is configured to work with this Display you are shown a template as you would see on a textbook. The squares are the places where you enter the numbers. For example when you press the fraction key the calculator displays a the picture of a stacked fraction with one square on either side of the horizontal fraction bar. The square where the cursor is located and blinking appear dark. You start entering the numerator there, then you use the down arrow to move to the denominator. When fraction is finished you move the square away from the fraction to the main line using the right arrow key.

I hole this solves the annoying problem of the mysterious squares.

Please read the manual to learn about this feature so that you can decide whether to take advantage of it or not.

Hello,

Configure the calculator to be in MathIO : [SHIFT][MODE][1:MathIO].

Press the Integral key, the one judt beloe the [ALPHA] key.

The template of the integral appears, with the cursor in larger rectangle. Enter the function the screen displays the integral, a small upper sqaure, and a small lower square. The left parenthesis of the function is already supplied by the calculator.

Press [ALPHA] X to enter the argument of the function.

Press the right parenthesis.

Remain the limits.

Use left arrow to move the cursor just before the s of sin and press down arrow to enter a numerical value for the lower limit.

Press the up arrow to move cursor in upper square.

Key in the numerical value of the upper limit.

Press [=].

Warning. To have meaningful result, make sure the angle unit used is conform to the problem you are trying to solve.

Hope it helps.

Hello,

I found a way to show you how to enter it on your calculator. Make sure you are in Math Input Output (MathIO). To effect that press [SHIFT][MODE][1:MathIO]. Calculator clears its screen

Press [SHIFT] then [Fraction template key] the one just below [calc]. I will show an image of the template in a picture below. Then you enter 4.6x85000 in the upper square of the template. Press the [Down Arrow] to move cursor to the lower square and key in 3570x0.0843. Then use [Arrow right] to move cursor to the level of the fraction line and press [=]. Hope it helps.

Hello,

I am aware that the solution provided below is valid for the CFX/FX-9850G/GB/ but I will supply it. I remain convinced it will help you for your calculator.

In the main menu select [STAT] icon to enter Stat mode and display the statistical data lists. Use the satistical data lists to input data and perform statistical calculations. Use the arrows to move the highlighting around the lists.

Exemple: Enter the following values in List 1

1st line enter 90 [EXE]

2nd line 85 [EXE]

3 79 [EXE]

4 75 [EXE]

5 70 [EXE]

6 68 [EXE]

7 56 [EXE]

When finished you press [F2:Calc], then [F1:1Var] and the statistical results appear on screen.

Title of screen : 1-Variable

x bar =74.7142857

Capital Sigma x= 523

Capita Sigma X squared = 39851

x lower case sigma n = 10.5249945

x lower case sigma n-1= 11.3682934

n = 7

Scroll down with Down arrow to access other data

minX =56

Q1=68

Med =75

Q3=85

Xbar -x lower case sigma n =64.1892911

x bar + x lower case sigma n = 85.2392802

maxX=90

Mod=90

All you have to do now, is to look at the theory you learned and interpret what these values mean.

Hope it helps.
