You can refer to a function by going to [vars] then right then 1.

you can chose the functions you want from there.

so now you can make Y3 = Y1 * Y2 and it will work (but it will be noticeably slow)

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.

Good luck!

In theory yes. If you have a function y=f(x) and another y=g(x), an intersection point of the graphs of the two functions,** if it exists, **is a point (x_i,y_i) such that **f(x_i)=g(x_i)**.

Graphically this means that**(x_i, f(x_i))=(x_i, g(x_i))**: The two curves pass through the same point in the Cartesian plane.

Now consider**f(x_i)=g(x_i)**. That is an equation in x_i, or lest us just drop the _i to shorten and write f(x)=g(x), or **f(x)-g(x)=0**.

If you can feed it to the SOLVER in**EQN**, the equation mode, and the calculator gives you the roots of the equation, then for each root x_i found you have an intersection point (x_i, f(x_i)), or (x_i, g(x_i)). You can use either function to calculate the y-value since the two functions are supposed to be equal at the root x_i.

**However it is much simpler to do with a graphing calculator.**

You must cast the functions in the so-called functional form y=ax+b. Isolate y for both functions, then open the Y= function editor and type in the second member (right member) of y=ax+b.

You can enter both functions and have them graphed on the same screen. In that case one will be on the Y1= line, the other on the second line.

Make sure that both = signs in the Y= editor are highlighted if you want both functions on the same graph.

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).

You must disable the Statistical plots.

- Press STAT button
- In the menu list that displays, select the Option PlotsOff and press ENTER.
- When the calculator answers Done, you can go to Y= editor to enter your functions or
- press GRAPH, if functions are already defined.

You must deactivate the Statistical plots.

Press [STAT].

In list that is displayed delect [4:PlotsOff] and press [ENTER]

Go to [Y=] editor to enter functions or press [GRAPH] if functions already entered.

Hello,

**First thing to do before any new type of problem**

1. Turn StatPlots OFF : press [2nd][STATPLOT][4:PlotsOff] [ENTER]

**Second thing: Clear the statistical lists**

2. Press [2nd][0][PGRM] DownArrow to point to ClrAllLists.

3.Press [ENTER][ENTER]

**Third thing : Configure the graph type to be FUNCTION graph**

4. Press [MODE]. If FUNC (on fourth line) is highlighted. Press [Y=] and start entering the functions.

5. If FUNC is not highlighted, use Down arrow till 4th line, highlight FUNC and press [ENTER]. Press Press [Y=] and start entering the functions.

**Fourth thing: Enter function and select them for graphing**

1. As you start entering the function Y1=, notice that the = sign becomes highlighted. Press [ENTER] when Y1 is typed in. Make sure the = sign for Y1 remains highlighted as cursor moves to Y2=.

2. Keep entering the functions and verifying that their = signs remain highlighted as cursor moves to another equation.

3. When finished press [ENTER]

4. Look at the graph style for each function: it is a bit of line to the left of each Y. Here is a picture of all the 7 styles.

To set a graph style, highlight the style to the left of the Y, and press [ENTER]. Each time you press [ENTER] you see a new style, in the order shown on picture.

Avoid the style of Y6, it is bubble, and as such will burst and disappear once graph is finished. Avoid also the triangular ones (for Y3 and Y4) they will shade areas of the graph, and may hide other functions.

**Fifth thing: Graph Functions.**

1. You can press [GRAPH] to see your graphs.

2. If one curve is missing (and you have not set its style to be rhe bubble), it may be due to the Window dimensions.

**Sixth Thing: Set Window dimensions and Zoom.**

1. Press [ZOOM][6:ZStandard] to use standard window dimensions.

2. If curve still missing, Press [ZOOM][3:Zoom Out] to zoom out so that you may be able to see a bigger range for the functions.

3. If necessary press [WINDOW] and set the Xmin, Xmax, Ymin,Ymax to values of your own.

Dimensions must obey the conditions: Xmin < Xmax, and Ymin < Ymax.

Hope that helps.

Hello,

The marking that so puzzle you define the type of line (or dots) to represent the graphs. Enter as many functions as there are Y variables.

After entering a function press [ENTER] to jump to the next one.

When finished entering all functions press GRAPH. If you want graphs drawn one after the other, in MODE highlight Sequential (6th line) and press ENTER. If you want graphs drawn simultaneously, in MODE (6th line) highlight Simul and press ENTER. Press 2ND QUIT to return to previous screen . Execute graph again.

Hope itr helps.

On the TI-84 there is an application called Transfrm. When active it prevents you from graphing multiple functions at the same time. To fix this, select Transfrm fom the APPS menu (it was at the bottom of mine) and select 1:Uninstall. That should fix the issue
