Imaginary Unit Pillows
Description: A diagram illustrating Euler's formula (e^iφ = cos φ + i sin φ) on a complex plane with a unit circle. It shows the real (Re) and imaginary (Im) axes, a point P on the circle, and the angle φ, with labels '0', 'cos φ', and 'sin φ'. Below the diagram is Euler's identity: e^(iπ) + 1 = 0.
