Question about Casio FX-9860G Graphic Calculator

I'm learning how to use the fx-9860G Slim Graphic Calculator. I'm following the example in the manual to graph y=3x^2. I enter graph from the menu, input 3, x theta T, x^2, exe. Then I hit F6, draw.

The calculator flashs the function at the top of the display screen and then a thick dark line appear across the bottom of the screen. This happens in conics, too. But I can get it to draw plots in the STAT mode. I've changed the battery and poked the P key.

What am I doing wrong?

Hi,

a 6ya Technician can help you resolve that issue over the phone in a minute or two.

Best thing about this new service is that you are never placed on hold and get to talk to real repair professionals here in the US.

SOURCE: Inputing factors on a casio fx-115es calculator

Unless I am failing to understand your problem, just combine like terms to get:

9x^2+2x+4 and then enter those coefficients into the quadratic solver.

That will get you the two answers -- both of them will be complex.

If you wanted to turn those two answers into factors (complex) of the original equation simply

change the signs on each and put an x in front.

Of course, the quadratic formula would also work.

SOURCE: Casio fx-9860g ............ how to do percent operation

Hello,

[OPTN][LIST] scroll right till you find %. Press the function first then the number. It gives you the percent.

Hope it helps.

Hello,

I do not understand what you mean by solve complex equations, but if you want to manipulate complex numbers here are the tools you need to enter your complex numbers. Operations and function evaluations do not need special symbols.

Hope it helps.

SOURCE: how do i generate random numbers on the casio

The random number generator function is called Ran# and can be accessed
in RUN mode by pressing:**[OPTN] [F6] [F3] (PROB) [F4] to access the (Ran#)** function

In the paragraph above, the **bold text** in square brackets indicates key presses,
while the text in parentheses represents the menus that appear at the
bottom of the calculator screen. This also assumes there are no menus on
the bottom of the screen when you begin. If PROB is already on the
screen, then the [F6] key is not necessary, just press [F3] then [F4] at
this point.

The Ran# function generates a random decimal number
between 0 and 1. If you need to generate a number with a higher range,
then there may be extra steps involved. For example, to choose a random
number between 0 and 100, you would enter:**Ran#×100 or Ran#(100)**Let's
say you want to simulate a dice roll, where you get an integer between 1
and 6. Your first step would be to do:

This will give you a random decimal number between 0 and 6. But we need an integer, not a decimal. To make it an integer, you would change this to:

Press

This now gives you an integer between 0 and 5. We just need to add 1 to the result.

The result should be an integer between 1 and 6.

A linear function in standard form is of the form Ax+By+C=0, where A is a positive integer, B and C are integers (positive or negative).

The problem is that calculators graph a function given in functional form y= ax+b.Thus to graph a function in standard form by means of a graphing utility you must isolate the y variable. The interesting thing about the Prizm (Casio graphing calculator) is that you select which variable to isolate y (usually) or x if you so choose. To choose to graph the function x=Dy+E you must select the function type as X=.

All graphs, except the linear function y=ax+b, are non-linear. To graph a function, just enter the GRAPH utility, type in the functions Y1=, Y2=, ... and press the Draw tab.

There is a program called Prime Factor Analysis on this site. It is written for the FX-9750GPlus calculator but I suspect you should be able to use it on the FX-9860G. To access the site you must have an account. You can register and it is free.

-15x^4 / 3x = -5x³ for x 0.

You should be able to figure this out without having to resort to a calculator. Note the "for x 0"... the two functions are identical everywhere, except the -15x^4 / 3x version is undefined for x = 0 (3 times 0 is 0 and you cannot divide by 0). The function has a "hole" at this point. -5x³ does not suffer from this defect, for x=0 it simply evaluates to 0, so you have to mention this fact to make it proper.

I am not sure how you can create such function (the range limitation do not work for x=c) but you can draw a vertical segment, just do not call it a function.

Draw a graph Y1=0

Then press SKETCH function key and use the F6 key to cycle through the TABS at the bottom of the screen. Look for the TAB named PEN. and click the function key below it.

Use the arrows to move the cursor to a spot on the screen (near the bottom), Press EXE to fix the starting point of the segment. Then use the Up arrow to draw a vertical segment from bottom to top.

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.
