Question about Casio CFX-9850G Plus Calculator
For example, I would like to convert 2+3i into polar form, and back again. I know that with some calculators you can do this, but I haven't been able to find any information for the Casio CFX-9850GB. Thanks!
To convert a complex number (not an equation) from rectangular coordinates to polar coordinates you do as follows
2+3[OPTN][ F3 (CLPX)][F1(i)][F6 >][F3> r ,theta][EXE]

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)
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
