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

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

I just realized that your question pertains to the FX82MS but is listed under the FX115ES (That is quite a difference) So my answer above does not concern you but I will leave it as is should anyone need the answer for the FX115ES.

Look at the enclosed screen capture for the FX82MS

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

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.
