Instant download — Euler's Identity as a scientific-plate art print. Walk the unit circle: e^(iθ) = cos θ + i sin θ. A quarter turn lands on i, a half turn on −1 — so e^(iπ) + 1 = 0, one line tying together e, i, π, 1 and 0, arguably the five most important numbers in mathematics. Every line is computed from the mathematics — not stock art, not AI. What you get (instant download): one ZIP with 5 aspect ratios (2:3, 3:4, 4:5, 5:7 and ISO/A) at 300 DPI — print small or large, at home, a print shop, or an online lab. For personal use. Frame not included.
