This symbol represents a function that takes in a complex number, and outputs the real part of that complex number.
This symbol represents a function that takes in a complex number, and outputs the real part of that complex number. For example, \(\Re(a + b\htmlClass{sdt-0000000129}{j}) = a\).
The symbol \(\Re\) represents a function that takes in a complex number, and outputs the real part of that complex number. For example, \(\Re(a + b\htmlClass{sdt-0000000129}{j}) = a\). To emphasize this, the real part of a complex number is always a real number itself.
