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]

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

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

There is nothing to convert, because if T is a real number so is 40sin(4000T).

40sin(4000T)=40abs(sin(4000T))*sign(sin(4000T))

where**abs()** is the absolute value of it argument, and sign(sin(4000T)) is positive or negative.

So in (radius, angle) polar coordinates

r= 40 abs(sin(4000T)),

theta =(0, or PI), depending on sign(sin(4000T))

If you are trying to graph parametric functions, this calculator does not do graphs, and you need another function of T

40sin(4000T)=40abs(sin(4000T))*sign(sin(4000T))

where

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.

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).

Use the >Rec and >Pol commands. They're in the Complex number menu, accessible through 2nd [CPLX] MORE.

[CPLX] is the shifted function of the 9 key.

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.
