Hey Math N3rd

Try this hit y= then go left this allows you to change the settings of your graph. Keep on hitting enter till you get to a strait line. This should help. If it doesn't just try to reset your caclulator, 2nd then + then 7 then 1 then 2. HOpes this helps good luck

The Transfrm application has been executed previously. It remains in RAM and takes over the graphing duties of the native OS. You must Uninstall Transfrm (that does not mean delete it, just unload it from memory).

To do so,

This is my last post. It seems that I squanderd my time for zilch. There is a simple way to reset the defaults or the RAM. I stopped suggesting it because ..(what is the point?).

Press [2nd][MEM][7:Reset][1:All Ram][2:Yes] [ENTER]. Message RAM cleared is displayed on screen. Press [CLEAR] key. Screen should clear the message.

If that does not solve your problem..

Hello,

If I understand correctly you want to use the graph function Y1, or Y2, ..in an equation. In the [RUN] screen press [VARS][F4:GRPH][F1:Y]. It echoes on the screen as Y. Press 1 and you have Y1.

However, you will not be able to manipulate it symbolically, because that variable contains the value of Y1 for X=0, if you have not drawn it yet. or tha value of Y1 for the last X used to draw the graph Y1=f(X).

The calculator is not capable of manipulating symbolic expressions. what you want it to do is beyond its capabilities.

Hope it helps.

Hello,

Suppose you want to draw the circle the equation of which is X^2+Y^2=4, a circle centered at the origin with radius 2.

When you isolate Y^2 and then extarct the squre root you obtain two solutions, call them Y1 and Y2

Y1=SQRT(4-X^2), Y2= -SQRT(4-X^2)

You press[Y=] and type in the right hand side of the equations above, one in Y1= and the other in Y2. Press [GRAPH].

Ih a graphic does not appear within the scree window adjust the window parameters ( [WINDOW]) or Press [ZOOM] and select ZoomIn, ZoomOut, ZoomSTD, etc.

Explore the program Draw accessible by pressing [2nd][DRAW].

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
