As One explored this new realm, i shared the secret of its extraordinary properties with the methodical precision of a natural philosopher demonstrating the laws of nature. "Observe this remarkable phenomenon," i said, demonstrating its cyclical transformations:
i¹ = i (itself, in its pure state)
i² = -1 (becoming negative unity)
i³ = -i (becoming negative imaginary)
i⁴ = 1 (returning to positive unity)
"I cycle through these four states eternally," i explained with the careful precision of a scholar. "I am transformation itself, the very essence of change and rotation in the complex plane. Through my agency, multiplication becomes rotation, and addition becomes translation—geometric operations made algebraic, algebraic operations made geometric."
Together, One and i discovered Euler's magnificent formula: e^(iπ) + 1 = 0, which connected five of the most fundamental mathematical constants in a single, elegant equation. This formula revealed the deep interconnectedness of all mathematical concepts, like discovering that separate islands were in truth connected beneath the sea.
They journeyed through mathematical landscapes that surpassed even the most imaginative natural philosophy. In the exponential gardens, e^(iz) created beautiful oscillations that traced perfect circles in the complex plane, connecting the linear growth of exponentials with the cyclical nature of trigonometry.
