### 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.

### 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 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.

Rec(3, Pi) gives X=-3, Y=0
Hope it helps
