Web27 feb. 2024 · Comparing W just above with w in Equation 1.14.1, we see that W is indeed the matrix corresponding to the complex number w = z1z2. Thus, we can represent any complex number z equivalently by the matrix. Z = [Rez − Imz Imz Rez] and complex multiplication then simply becomes matrix multiplication. Further note that we can write. Web11 mar. 2015 · 10. I know that given two complex numbers z1 = a + bi and z2 = c + di, the multiplication of these two numbers is defined as. z1 ∗ z2 = (ac − bd) + i(ad + cb) I also know that I can easily derive this formula by applying the distributive property of multiplication and considering i2 = − 1. But i2 = − 1 is a consequence of the definition ... Web28 nov. 2015 · So if we multiply two complex numbers together, e.g. $z=re^ {i\theta}$ and $w=se^ {i\phi}$ we get $$zw = re^ {i\theta}se^ {i\phi}= (rs)e^ {i (\theta+\phi)},$$ so as you can see the resulting complex number has angle $\theta+\phi$ and length $rs$.
