The Complex Plane

Complex numbers are one of the most interesting and beautiful topics in mathematics.

1. Impossible Solutions Imaginary numbers were originally called “impossible numbers” because they were solutions to problems that did not have real solutions.
2. Multiplying Triangles Did you know that you can multiply triangles? This is the first hint at the actual meaning of imaginary numbers.
3. The Most Beautiful Formula in Math e^ip + 1 = 0
