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

    First set casio fx115es to complex mode, which is done by clicking on mode then #2. 2nd, make sure you casio is set to Degree not Radian or anything else. Do this by clicking Shift then mode then click #3.

    So, if you have a rectangular problem like this: 3.866+j1.013 --- and you want to turn that Rectangular to polar, you would hit Shift then + key (POL - for polar). Then type in 3.866 then hit shift comma, which is the closed paranthesis then type in 1.013 then close the paranthesis. So, on your Calc screen it would look like this

    Pol ( 3.866, 1.013)

    answer would look like this:
    r = 3.99673
    0 = 14.6952

    The zero above represents Theta. Hope this helps.

How to add polar and rectangular form on calculator?


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.

How do I add or subtract numbers in polar form or rectengular form


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.

Polar to rectangular conversion working incorrectly


At first, Rect and Polar are a display-format instructions, not a conversion functions. Polar instruction displays complex value in rectangular form a + bi. The complex value can have any complex form. However, an r*exp(i*theta) causes an eror in Degree angle mode according to the TI avowal. See captured images below

Conversion of polar to rectangular form and vice versa


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]
Conversion of rectangular to polar:
  • 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]

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.
