Question about Texas Instruments TI-84 Plus Calculator

It is a function if it passes the verticle line test. That is if you graph a problem and a verticle line passes through the problem only once then it is a function. If the verticle line passes through the problem more than once it is not a function.

At first in Y editor type **Y1=2*cosx** and for example **y2=[5*exp(-x)]-5** and then graphing it. Set **RAD** mode of course. See captured images

As you can see this function have zero values in the points -2, -1 and 4

You're probably trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

If this doesn't do it, please reply to this post and give a sample equation that causes this error.

To enter powers of trigonometric functions you must enclose the functions in parentheses and then apply the exponent to the whole. For example X1t =(sin T)^3 , Y1t=(cos T)^3 will give you a shape similar to a rhombus with concave sides. The symbol ^syands for the operation of raising to a power. The key is the one with the caret symbol ^ , and it is wedged between the xsqure and EXIT keys (third row of keys).

As regards the cotangent, use the equivalent definition cot(X)=1/tan(X).

If the message appears when you try to graph functions deactivate the
statistical plots. To do so:

Press [2nd][Y=] to access (STAT PLOTs)

Select [4:PlotsOff] then [ENTER]

That should solve your problem. Post a comment to this thread if you still have trouble graphing.

If the message appears in another context, it sure would help knowing the context of the error.

Hello,

[2nd][MEM][7:Reset][1:All ram][2:Reset] [ENTER]. Screen shows RAM cleared. Clear the screen and use [Y=] to enter the functions you want to graph.

Hope it helps.

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)= ...)

I think you should get a Texas Instruments calculator and push the 'y=' button then put the equation like '2x+4' in the y1 area. You can put the X by using the variable botton. I hope my english makes sense I am not a native speaker.
