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

You cannot add rectangular coordinates to polar coordinates. You can **only add rectangular coordinates to other rectangular coordinates.** For polar coordinates you must use some specific trigonometric formulas.

If one or both numbers are in polar form, convert it/them to rectangular. Once both numbers are in rectangular form, simply add the two components separately: Add the two x components together, and add the two y components together.

If you're asking how to do this on a particular calculator, please specify the make and model.

I would be interested in knowing the model number of the Casio calculator that can do prime factorization. I know and own several Casios (scientific and graphing) calculators and I have not found one that does it. Some graphing calculators are able to perform the factorization with the help of an additional program.

Conversion of polar form to rectangular:

- Switch to CMPLX mode: [MODE] [2]
- Enter complex number in polar form, e.g. r = 3, θ = 42°: 3 [SHFT] [(-)] 42 [=]
- Switch to rectangular view: [SHFT] [2] [4]

- Switch to CMPLX mode: [MODE] [2]
- Enter complex number in rectangular form, e.g. real part = 2, imag part = 3: 2 [+] 5 [ENG] [=]
- Switch to polar view: [SHFT] [2] [3]

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.

Are you serious?

No calculator purchase should be solely based on such a trivial matter.

But if you are looking for a very good scientific calculator, I would suggest the new Write View EL-W506/W516/W546 calculators by Sharp, or the FX-115ES/991ES Natural Display by Casio.

With these calculators you can see what you enter displayed as in textbooks. Naturally, they all do coordinates conversions from Polar to Rectangular and from Rectangular to Polar.
