OverlineBA

OverlineBA is a mathematical notation used to represent the complex conjugate of a complex number. It is denoted by placing a horizontal line, or overline, over the complex number. For example, if z = a + bi, where a and b are real numbers and i is the imaginary unit, then the complex conjugate of z is denoted as z with an overline, written as z̄ or z̅. The complex conjugate of a complex number z = a + bi is given by z̄ = a - bi. This notation is particularly useful in various areas of mathematics, including algebra, calculus, and complex analysis, where complex conjugates play a crucial role in simplifying expressions and solving equations involving complex numbers.
