Question about Casio CFX-9850G Plus Calculator

Please help.

Hello,

Here how you do it taking as exemples y1=x^3 -5 and y2=abs(x^3-5)

Turn calculator ON by pressing [AC/On] . Use arrows to select [Graph] icon and press [EXE]

On line Y1= enter X[^]3 -5 [EXE]

On line Y2= press [OPTN] [F5:NUM][F1:abs] [(] X [^]3 -5 [)] [EXE]

The graphs will be drawn one after the other. You might have to adjust the window limits.

Here is an ouput drawn on another calculator.

For negative values of the x-variable, Y1 has negative values, while in the same range, Y2 has positive values, equal and opposite to those of Y1. In that range, Y1 and Y2 are symetric of each other with respect to the X axis.

For positive values of the x-variable, Y1 and Y2 are identical.

Hope it helps

There is nothing to convert, because if T is a real number so is 40sin(4000T).

40sin(4000T)=40abs(sin(4000T))*sign(sin(4000T))

where**abs()** is the absolute value of it argument, and sign(sin(4000T)) is positive or negative.

So in (radius, angle) polar coordinates

r= 40 abs(sin(4000T)),

theta =(0, or PI), depending on sign(sin(4000T))

If you are trying to graph parametric functions, this calculator does not do graphs, and you need another function of T

40sin(4000T)=40abs(sin(4000T))*sign(sin(4000T))

where

To access the absolute value command, got to Run/Mat screen and press OPTN. Press F6> the F4:NUM, then F1:Abs

In the Y= entry screen, press OPTN, then F5:Num, F1:Abs. enclose the argument of the function inside parentheses.

Here are two screen captures to show how it is done.

To use the asolute function you go to the RUN screen, press OPTN, then F6> to ge to next screen with a TAB called NUM. Press F4 to open the NUM tab. The Abs function is above the F1 key. See the screen capture to help you for graphing.

If you want to graph the absolute value of a function, feed the function to the absolute value ie graph y= abs(f(x)). The calculator will take care of it. See screen captures where I draw the function y1=x^3-5x^2-3 and y2='x^3-5x^2-3'. On the first graph the function is represented and on the second the function and its absolute value.

The calculator knows how to calculate the absolute value of an expression. The name of the command is abs(

You'll find the absolute value function in the MATH menu.

Hey it is. Okay, so start with a equation: say, y = -(1 |x|).
Now type y = -(1 , then press the [OPTN] button, next to the shift. Next press the [NUM] button or F5. The first menu button should be Abs or absolute value. When your done it should look like this.
y = -(1 Abs (x)) then graph it.

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.

Absolutely! Here's how:

-Make sure the function is in the form f(x)=.... (treated as y=...)

-Then, go to "y=" on your calc

-Plug in your equation (using x as your other variable regardless of whatever your book/worksheet uses)

-Hit "graph"

-For Domain, look at possible limitations on x values (does it stop at 3 no matter what? are there no limitations? etc)

-For Range, look at limitations on y values

Hope that helps! :-)
