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.

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 form to rectangular:

- Switch to CMPLX mode: [MODE] [2]
- Enter complex number in polar form, e.g. r = 3, θ = 42Â°: 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]

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.
