The \real command in LaTeX is used to denote the real part of a complex number. It is typically used in mathematical expressions to extract or represent the real component of a complex number.

Examples

ℜ (z)

Extracts the real part of the complex number z.

\real(z)

ℜ (3 + 4 i) = 3

Represents the real part of the complex number 3 + 4i, which is 3.

\real(3 + 4i) = 3

I f z = x + y i, t h e n ℜ (z) = x

General representation of the real part of a complex number z = x + yi.

If z = x + yi, then \real(z) = x
