Is it complex or matrix? You can have only one mode at a time.What kind of equations? The solve function uses real-valued equations.

Complex numbers: You can add, subtract, multiply and divide. You can convert a number from rectangular to polar forms and vice-versa; you can calculate the absolute value of a complex number, or a conjugate.

All the operations are done in the Mode CMPLX.

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 = 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.

There isn't one. If you're entering a complex number in rectangular form, separate the real and imaginary parts with a comma (left of the 4). If you're entering a complex number in polar form, separate the magnitude and the angle with the angle symbol (2nd comma).
