Question about Casio CFX-9850G Plus Calculator

1 Answer

Convert a polar equation to a rectangular equation?

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!

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

Polar rectangular


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

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.

In Run screen, Press OPTN, Press F6> repeatedly until you see the ANGL TAB. Press F6> again (once or twice). You will see the TAB Pol( and Rec(
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).

How do I convert between the rectangular and polar form of a number with imaginary values? i.e. I want to take the number a+bi and convert it to polar D<(angle) and vice versa.


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.

Polar/rectangular


For a TI-86


Converting rectangular to polar
Press "2ND" and then "MORE" for the MODE screen
Highlight PolarC and press "ENTER"
Quit that screen.
Now ready to go.
A example of converting 5+j6
Enter "(5,6)" in the calculator and press "ENTER"
Should get (7.81024967591*angle*50.1944289077)


Converting polar to rectangular
Press "2ND" and then "MORE" for the MODE screen
Highlight RectC and press "ENTER"
Quit that screen.
Now ready to go.
A example of converting 5*angle*35
Enter "(5*angle*35)
Should get (4.09576022145,2.86788218176)


Note
*angle* is the symbol when you press "2ND" then ","


Note 2
To round the an decimal places press "2ND" then "MORE" for the MODE screen and on the line that says float, choose a number on that line for the number of decimal places you would like to have.
