G. CPLX

Since complex numbers are not generally covered in algebra, trigonometry, or the first two calculus courses, this topic is given just a cursory introduction.

A complex number consists of two parts. In rectangular form a complex number is entered in the format: (real,imaginary).

The following options are offered in the CPLX (Complex Number) Menu. Access the CPLX menu by pressing . These examples are for rectangular mode only and only the more common functions are shown below.

conj

Gives the complex conjugate of a complex
number, a list, a vector or a matrix.

real

Gives the real part of a complex
number, a list, a vector or a matrix.

imag

Gives the imaginary part of a complex
number, a list, a vector or a matrix.

abs

Evaluates the magnitude of a complex
number, a list, a vector or a matrix.
