Modulus of z 2
WebThe modulus or magnitude of a complex number ( denoted by ∣z∣ ), is the distance between the origin and that number. If the z = a +bi is a complex number than the modulus is. ∣z∣ = a2 +b2. Example 01: Find the modulus of z = 6 +3i. In this example a = 6 and b = 3, so the modulus is: Web5 mrt. 2024 · In other words, \(i\) is a solution of the polynomial equation \(z^2+1=0\), which does not have solutions in \(\mathbb{R}\). Solving such otherwise unsolvable equations was largely the main motivation behind the introduction of complex numbers.
