Draw the graphs of the functions you are interested in. While the graphs are displayed Press the Menu key. In the drop down window locate the submenu Settings (number 8 or 9) depending on your calculator

The following screen is displayed with at the top the setting Float.

Follow the right pointing arrow on the same line as float and select Float 3 or 4 as on the screen capture above.

Point to the graph of one of the functions select it then press the menu select option Analyze graph then intersection. You will be asked to select the second function, then the lower bound and upper bound. As you see on the previous screen capture, the coordinates of the intersection point are given with 3 decimal digits.

There is no such error message from the TI 83PLUS. Did you mean WINDOW RANGE?

The easiest way to correct the messed up window dimensions is to reset them. You can press the Zoom button and select 6:ZStandard

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.

You can try to reset the calculator: In so doing the default configuration is restored. If that works for your graphs why fiddle with the setting?

Ok to reset calculator (do not worry I will tell you how to change window dimension):

Press [2nd][+] to access the (MEM)ory management.

Press [7:Reset][2:Defaults] [2:Reset]

The window dimension will be restored.

To change dimensions

In main calculator screen press the [WINDOW] function key

Enter the value of Xmin. If negative use the change sign key (-) under key 3

Enter Xmax value. Make sure that Xmin is less than Xmax.

Leave the Xscale at 1

Enter Ymin. If negative use the change (-) key

You can leave the Yscale at 1, Xres at 1.

You can change the DeltaX but if you take too small a value your graphs will take long to be drawn.

If you ever get a problem, just press the [ZOOM] function key and select [6:ZStandard] it will restore the default dimensions.

Try using the standard Zoom.

If you are drawing Y=f(X) functions, press [ZOOM][6:ZStandard]. The window dimensions will be [-10, 10] for X and the same for Y.

If you are drawing polar graphs, in addition to the X,Y windows dimensions, you have Theta min =0 and Theta max =2*Pi =(6.28)

If you are drawing Y=f(X) functions, press [ZOOM][6:ZStandard]. The window dimensions will be [-10, 10] for X and the same for Y.

If you are drawing polar graphs, in addition to the X,Y windows dimensions, you have Theta min =0 and Theta max =2*Pi =(6.28)

Hello,

Xmin is the smallest value of variable X: by default it is -10.

Xmax is the largest value of variable X: by default it is 10.

Ymin is the smallest value of Y default is -10.

Ymax is the largest value of Y default is 10.

You set these values according to the area of the graph you want to see.

If X is always positive, you can set Xmin=0.

If function values are laways positive, eg y=x^2, Ymin=0.

Xscl =1 by default. There will be a tick mark on the X-axis for each X integer.

YScal=1: there will be a tick mark for each integer value of y. If you want tick marks every 0.5 you set Yscal=0.5

Xres=1. Calculator calculates y values say at X, X+1, X+2, etc.

Hope it helps.

Hello,

Reset calculator to defaults

[2nd][MEM][7][2][2] Defaults set.

[Y=] on line Y1= enter your function then press [GRAPH]

You can draw several graphs on the same screen.

If nothing shows (except the axes) use [ZOOM] to Zoom in or zoom out or use [WINDOW] to change the values of Xmin, Xmax, Ymin, Ymax.

Hope it helps.

Press the WINDOW key on the top row and change the values to suit the particular function you're graphing.

have you tried to change the window????

there is a second function over one of the f buttons which has window....

most likely you put the negative number for the max and the positive number for the min x or y value!

if all else fails....

RESET IT

there is a button on the back which will just clear all your settings...
