SOURCE: 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

Screen displays

Y=2.524532346

If angle is in radians, [SHIFT] [MODE][4:Rad] the command

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

Hope it helps

Hello,

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= 1.414213562θ= 45 **

Rec ( radius, angle) =

Exemple: Recatngular coordinates of (r=3, θ=60°)

The screen displays

X= 1.5

Y= 2.598076211

You can switch the display mode for complex numbers by pressing SHIFT MODE down 3 and picking one. This will display the current result in the selected mode.

You can also override the current display mode and specify the format. Add these keystrokes at the end of a calculation: SHIFT 2 then 3 for polar or 4 for rectangular.

To convert from Polar to Rectangular

PRESS [SHIFT and -Rec] then enter the coordinate and angle

e.g. [SHIFT and -Recl]

Rec(15,0)=

r=15

0=0

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.

Use the Rec function (shift of the - key).

Rec(r,t) converts a polar value of magnitude r and angle t in the current angular mode. The real value is assigned to X and the imaginary value is assigned to Y.

Use the Pol function (shift of the + key) for the reverse.

It's on page E-37 of the manual. If you've misplaced your manual, you can download a new one from http://www.casio.com/support/manuals
