WebSep 16, 2024 · Definition 6.1.2: Inverse of a Complex Number. Let z = a + bi be a complex number. Then the multiplicative inverse of z, written z − 1 exists if and only if a2 + b2 ≠ 0 and is given by. z − 1 = 1 a + bi = 1 a + bi × a − bi a − bi = a − bi a2 + b2 = a a2 + b2 − i b a2 + b2. Note that we may write z − 1 as 1 z. WebThe complex conjugate of a complex number is defined as the number we get by replacing all factors of i by –i in the formula for the number. We generally denote the complex conjugate by placing an asterisk after the number. For example, if z = x + iy, then z * = x – iy. If we start with z = r exp(iφ), then z * = r exp(-iφ). Task 4:
