What is the distance between the complex numbers 1 + 3i and 2 + 4i in the complex plane?

November 18, 2024 by devyy

To find the distance between two complex numbers in the complex plane, we can treat them as points in a two-dimensional space. The complex number 1 + 3i corresponds to the point (1, 3) and 2 + 4i corresponds to the point (2, 4). We can use the distance formula, which is derived from the … Read more
