When you graph a function and press F4, it will clear up giving you an empty coordinate graph. Mine won't go away. I can still graph other functions, but this one won't go away

If you [green diamond] key and [F1 y=] you can select the function or plot that are on to off using the [F4 check mark or deselect] key or [F5 All] key and [1] key will turn off all functions and plots until the next command to turn them back on again. Because you mentioned this graph just won't go away leads me to believe its plots that may be on but, you said you can add functions which kind of confused me because the plot is the same place as the y=function just above them. It is real easy to not even know the plot function is there much less even know if one is on. There is other possibilities but, my solution may or may not help you from having to clear drawing every the time. Then again if it is because of internal programs running the clear drawing is your better choice unless you know what now internally may be operating to causing your problem. Any programs you've been operating lately? Make sure you clear out your variables and equations before you leave the Numeric Solver APP, I've went through a lot of problems before I learned that.

Hope this helps you with your calculator!

Hello,

There is an instruction to clear graph

When in Graph mode Press [F6:Draw] and [1:ClrDraw].

Hope it helps.

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 sub menu 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 that follows

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.

Is it somehow preventing you from graphing, or are you simply not getting the graph you expect?

Most likely you have the angular mode set wrong. You probably want it set to radians. Press MODE, move to the third line, highlight RADIAN, press ENTER, then 2ND [QUIT].

If it's not the angular mode, please reply to this post and give an example or two.

Select two points P1 and P2 on the line. Read their coordinates P1(X_1,
Y_1), and P2(X_2, Y_2). If the points are given to you that is even better: you will not have to approximate their coordinates.

The slope of the straight line that passes through P1 and P2 is the ratio s=(Y_2-Y_1)/(X_2-X_1).

A slope is a number and cannot be graphed. The line that has the slope can be graphed if you have its complete equation y=slope*x + initial value.

To graph a curve on the TI84 open the Y= editor, type in the second member (right side) of the function say on line Y1= then press the Graph function key.

To calculate the definite integral (integral with specified lower and upper bounds)

Another way is to graph the function. While graph is displayed press SHIFT: F5:G-Solve, then F6>, Then F3:$(

Use arrow key to select the lower bound, then select select the upper bound. Press = to get result. The area concerned will appear shaded.

Note: There is a drawback to this method. The lower and upper limits must be inside the graph window limits.

- In Run/Math screen press OPTN
- Press F4:CALC
- Press F4:$ (integral)
- After the $( type in the function of X, enter comma, enter the lower bound, comma, upper bound, right parenthesis to close.
- Press =

Just return to the Y= function editor and type your function again. Press Graph or 2nd GRAPH and you will find your table.

What probably happened is the graph was turned off.
to turn the graph back on, select the function (ex. y1) and then press f4. This should turn the graph back on and you should see the function.

Hope this helps.

I am puzzled by the (-2,2) after the equation. I suspect it is the
coordinates of some point. But I won't push the matter further, and I
will just ignore that info. I am no mind reader.

- Turn calculator ON.
- If you do not see icons, press Menu.
- Use navigational arrows to highlight [GRAPH] and press [EXE]
- Type the function.

- Use the [X.T,theta] key below [ALPHA] to type the X variable or the [ALPHA][+]. In general you should use the [X,T,theta] because is context sensitive: If you draw parametric or polar graphs, pressing that key gives you the right variable (T, or theta)
- Use the caret [^] 3 to raise X to the third power and complete the function. and press [EXE]
- At the bottom of the screen you see some tabs.
- Press [F3:Type] and you will see all types of graphs you can draw. But since you want Y=, press [EXIT] to return to Y=editor
- Press the Function key to above which you see [DRAW]
- Adjust the Window dimensions if necessary

- While the graph is still displayed press [SHIFT][F5:G-Solve].You see all the possible calculationsF1:root, F2:Max,F3:Min,F4:YiCPT (y_intercept),F5:Isct (intersection) F6:=> to show the others, among which is the F3:integral.

- Press F3:min and hold your breath.

- After a while you get your minimun. Be patient, even if the small square at the top right disappears.

- Once you get the minimum, press [SHIFT][F5-G-Solve] and repeat for the maximum.

Instruction book for this calculator is shocking for sure. It would take too long to explain fully, here is an example of plotting a simple Y= graph.

In main menu, when you first turn it on, press 1

This is normal calculator mode.

Press [shift] [menu] to get the set up parameters.

Scroll curser down one to Func Type, and select Y= if this is not already set, by pressing F1

Continue scrolling down to set Coord, Grid, Axes and Label functions. Turn these on or off as desired. Turn them all off for this example. F1 and F2 select On or Off here.

Press [exit]

Press [shift] F3 to access the V-window parameters. Here you set the size of the axis in the graph

Enter 0 for Xmin, 360 for Xmax, 0.1 for scale

Enter -1 for Ymin, 1 for Ymax, and 0.1 for scale

Press [exit]

Press [shift] F4 to enter graph plot mode (Sketch mode)

Press F1 then [EXE] to clear any previous graphs

Press F5 then F1 to select Y= type graph

Display should show Graph Y=

press [sin] [ X,0,T] (this key just under red alpha key) then [EXE]

Calculator should draw a sine wave, showing 1 complete wave

Try setting the parameters in Set up, Axes On, Label On etc to see the effect.

Hope this helps a little. Page 123 in book deals with graphing.

Hello,

Let us start wih the derivatives. To obtain the values of derivatives at points on a graph, you must set** Derivative to ON**

Press [AC/On] to trun calculator on. If you do not see the icons press [MENU], with arrows select [RUN] and press[EXE] . The screen clears.

Press [SHIFT][SETUP ] . The first few options must be set as follows

Mode : : Comp

Function Type : Y=

Draw Type : PLot

**Derivative : ON This is the one to make derivatives visible**

Angle : Rad unles you have to use degrees.

Coord : on if you want the x,y coordinates to be displayed

Grid : Off

Axes : ON to display x and y axes

Press [EXE] to save options. You are taken to [Run] screen.

Press [Menu] Play with arrows to select [GRAPH] and press [EXE]

You see a list Y1=, Y2= and so on

On the line Y1=, enter [SIN] [X,Theta, T] .

If function is complicated you may have to enter parentheses sin(X). When you finish to enter the functions you want to draw, hit [F6:Draw]

The graphs are displayed.

Press [F1:Trace] The trace function allows you to move cursor along the curve, while it displays the coordinates of the cursor. And since you set Derivative to ON, the trace displays also the value of the derivative of the curve at the position of the cursor.

There are other intersting tools, under [Sketch] and [G-solve ] such as minimum, maximum, tangente, inverse of the function drawn, integral under the curve, intercepts with the coordinates axes, etc. I will not spoil your fun by giving you the plot of the movie.

Hope it helps.
