What does your graph look like? Do you have the proper angular mode set?

You have several types of graphs

**Function graph**s

Y_1=f(x), Y1=3X^2-4, [X, T, Theta, n] key types**X**

**Polar graphs** r=F(theta), r=r_o*ln(theta). [X, T, Theta, n] types **Theta **

**Parametric graphs** X_1=f(T) and Y_1=g(T). [X.T, Theta, n] types **T**

Examples: X_1= cos(T). Y_1= 2(1--sin(T))

**Sequence graphs **u_n+1= f(u_n), [X,T,Theta,n] types **n**

Y_1=f(x), Y1=3X^2-4, [X, T, Theta, n] key types

Examples: X_1= cos(T). Y_1= 2(1--sin(T))

Put the calculator in Equation solving mode. Select F3:Solver. Enter your equation; use X as unknow (no need to use Theta, the name of the variable is irrelevant.) Besides if you use theta you will get a syntax error.

When drawing function graphs of type Y1=, the name of the independent variable should be X

For polar graphs r=.., the independent variable is theta, while for parametric graphs it is T

To enter the default independent variable, press the key marked [X,Theta, T] . It will type in the correct name.

One simple way to define the domain to be graphed is to set the limits of the domain as the Xmin and Xmax dimensions of the window.

- Turn calculator ON
- If you do not see icons press the [MENU] key.
- Use the arrow keys to move focus on the [RUN] icon.
- Press [EXE]
- In RUN screen press the [OPTN].
- After you press the down key once you highlight the line "Func Type"

The polar graph type is set by pressing F2:r=. In general r=f(theta). After the F2 key is pressed the Function type changes to r=

Now, if you press the MENU key and use arrows to focus on and select GRAPH, the function entry screen looks as in the picture below (without the 2cos(3theta))

After you enter the function (use the (X, theta, T) key below the [ALPHA] to enter the theta variable) press EXE to validate.

After drawing the r1=2cos(3theta) curve I opted to change the function to r1=2cos(5theta)

Press F6:Draw to draw the graph. Here is what you get.

Enjoy.

Hello,

Turn calculator [ON]. If you do not see the menu icons, press [MENU]. Use the arrow keys to highlight the [GRAPH] icon.

An entry screen appears where you enter the functions you want to graph.

On the first line you have Y1= . After the equal sign enter 2[x] [X, theta,T] + 1. When finished press [F6: Draw] Your graph appears on the screen. If you see the axes, but no graph, press [Shift][V-Window] and press [F3:Std] then [SHIFT][QUIT] will take you back to the screen where you enter the functions to draw. There press [F6:Draw].

Hope it helps.

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.
