Hi,

a 6ya expert 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 repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

goodluck!

Add a graph .

In Documents Toolbox, select 3: Graph/Entry Edit

Unfold the menu and select Equation (not function). Enter your equation.

For the 3D part, I am afraid you will have to read the manual.

You need to set the graphing mode to 3D. In 3D graphing the function is represented as z(x,y)=function of the variables x and y.

Here are a few screen capture to show you how to set the thing up.

Read the calculator manual.

On the last screen are the parameters to change the point of view.

hi, you can purchase from http://calculator.runiter.com/graphing-calculator/buy-graphing-calculator.htm

let me know if it works.

Hello,

First you must configure your calculator to perform 3D graphics

Press MODE

1.The first line shown is**Graph**. Unfold the hidden menu list with the right arrow and choose **Graph 5:3D**

2. Press ENTER to validate.

Now you must define the surface you want to draw

1. Press the [diamond] key then [Y=] to get a list of function names, the first of which is z1

2. Enter the following function (or your own) z1=(x^3*y-y^3*x)/390

( x cubed times y -y cubed times x) divided by 390.

3 Press ENTER.

Graph the function

Press the [diamond] key then [GRAPH]

The graphing screen displays progress in %. When it is finished you will see a weird sombrero.

Hope it helps

The casio FX-300Ms calculator cannot do graphs. To tell you how to use a graphing calculator TO DRAW GRAPHS we need to know the exact brand and model number of the calculator.

- Most graphing calculators basically function the same way.
- You select the graph type (function, polar,parametric, sequence, 3D, wire mesh, slope field, etc.)
- You enter the algebraic form of the function you want to draw.
- You press a button or menu to GRAPH
- The graph is drawn.
- If you want to see a particular part of the graph, you use a ZOOM function, or you enter values for the WINDOW dimensions.
- Most graphing calculators have a TRACE function that allow you to follow the curve you have drawn to read off values of coordinate points.
- You can also use the calculator to find zeros roots) of functions, calculate derivatives at some chosen points or calculate the area "under the curve", find the minimum and maximum of a function.

I heard of instructor disabiling APPS but, not functions. One reason I can't see that is I can download a program that does the same thing and hide it w/ instructor even knowing its there unless he ran a search in ever folder or open a lot of programs

That means one (or more) of the variables you have in your function is not defined. Check to make sure you didn't misspell any variable name. Also, check to make sure you didn't run two variable names together. "ab" is the variable ab, not a times b.

I am not quite sure what you are asking...

(1) if asking for graphing y= -2/3x+2, then press [diamond] [F1: Y=] type in .2/3x +2, see graph by [diamond][graph]

(2) if asking for graphing y= -2/3x+a, where a=3x, then first archive a=3x in Home screen by [home], type 3x [sto] a, then go back to y= menu, and type -2/3x+a in Y1

(3) if asking for graphing an equation that is dependent on 2 variables at the same time, use x-y-z axis (aka, change mode to graphing 3-D by [mode]graph [5:3D]) then enter desired equation in y= menu using Z function in terms of x and y aka z(x,y)= ...)
