How do we change between X, T, Theta and n in the graphing calculator? I need the X, but it only inputs T....


Press the MODE button, select FUNC on the fourth line, then press 2ND QUIT.

FUNC gives you X, PAR gives you T, POL gives you theta, and SEQ gives you n.

How to use pol ?


The Pol function converts coordinates from rectangular to polar. Pol(x,y) converts the rectangular coordinates (x,y) to polar coordinates (r, theta).

For examples and instructions, see page E-37 of the manual and example #036 in the Appendix.

I need to convert the rectngular form to polar form , so how can i do that ?


In Run screen, Press OPTN, Press F6> repeatedly until you see the ANGL TAB. Press F6> again (once or twice). You will see the TAB Pol( and Rec(
To convert from Rectangular coordinates to Polar press POL(, type in the x and y coordinates then EXE
Example: F1: Pol(1,1) gives (1.314213562, 45)
F2: Rec(square root (2), 45) gives (1,1)
Make sure the angle unit is set to the one you need (degree or radian).

My calculator wont graph when it's set to POL (polar) in MODE! do i need to change something? if so, what? its a new problem but i need my calculator tomorrow!


Before graphing deactivate the statistical plots: Press [2nd][Y=] to access the (STAT PLOTS) configuration screen and press [4:PlotsOff][ENTER]

To draw polar graph, make sure in MODE, POL is highlighted.
Make sure that the angle unit is set to RADIAN
If you want the angle unit to be in degrees you must open the WINDOW editor to modify the values of Theta max to a significant value: 30, 45, 60, 90, 120, 180, 360, otherwise the calculator will take the default value 6.28 (2*PI) in degrees

How do you use the pol and rec


To avoid errors make sure that the angle unit is THE ONE required by your problem. To verify or to change the angle unit press [SIFT][MODE] and select [3: Deg] for degrees, [4:Rad] for radians, or [5:Grad] for grads.

Convert from rectangular to polar

[SHIFT][+] (Pol) . Screen displays Pol(
You enter the X-coordinate, and the Y coordinate separated by a comma, then you close the parenthesis and press [=].

Exemple: Polar coordinate of the point (1,1)
Pol( 1, 1) gives
r=1.414213562 (square root of 2)
θ=45

Here is how you enter it
Press [SHIFT][MODE][2:LineIO]
[SHIFT][POL] 1 [SHIF] [,] 1 [)] [=]

The screen displays
Pol(1,1)
r= 1.414213562
θ= 45


Convert from polar to rectangular coordinates

Rec ( radius, angle) =

Exemple: Recatngular coordinates of (r=3, θ=60°)
[SHIFT][Rec] 3 [SHIFT][,] 60 [ ) ] [=]
The screen displays
Rec(3,60)
X= 1.5
Y= 2.598076211

How to convert polar to rectangular form


Hello,
Press [MODE] and select [1:COMP]
Press [SHIFT][MODE] and select [3:Deg]. You can also use rad if the angle you are given is in radians.
To start the conversion
Press [SHIFT][-] (Rec) screen displays Rec(
Key in the radius r , ex: 3 screen displays Rec(3
Press [SHIFT][)] (,) to enter comma separator Rec(3,
Key in the angle in degrees, ex: 57.3; screen displays Rec(3,57.3
Press ) to close parentheses; screen displays Rec(3, 57.3)
Press [=]
Screen displays
Rec(3, 57.3)
X=1.620720961
Y=2.524532346

X and Y are the values of the coordinates.

If angle is in radians, [SHIFT] [MODE][4:Rad] the command
Rec(3, Pi) gives X=-3, Y=0
Hope it helps
