Complex Plane Crewneck Sweatshirts

Description: A diagram illustrating a unit circle on a complex plane with real and imaginary axes. It features vectors, trigonometric functions (cos φ, sin φ), and mathematical notations including 'ρ', 'ō = e^iφ', and 'e^N(ip) + 1 = 0'. The diagram is presented in white on a black background.

Description: Rendered on a deep dark background, this artwork presents the complex plane with the critical strip, the critical line Re(s) = ½ and the first nontrivial zeros of the zeta function, above ζ(s) = Σ 1/nˢ. In 1859 Bernhard Riemann conjectured that all nontrivial zeros of the zeta function lie on the line Re(s) = ½. The Riemann hypothesis, linked to the distribution of prime numbers, is still unproven today. Made for math teachers, mathematicians and students who love an elegant proof, it brings classic mathematics to a classroom, study or home office.

Description: A complex plane diagram showing the real and imaginary axes with a unit circle. Text labels indicate 'Re', 'Im', 'cos 0', 'sin 0', '1', '0', 'σ', and 'i'. An equation 'e^(iπ) + 1 = 0' is displayed prominently below the diagram, and another equation 'e^(iπ) – cos 0 + i sin 0' is at the top. The style is monochrome and geometric.

Description: A diagram on a black background illustrating complex numbers with a circle representing the unit circle in the complex plane. It shows vectors, angles labeled with 'theta', and mathematical equations including 'e^(i*pi) - cos 0 + i sin 0', 'e^(i*pi)', 'sin 0', 'cos 0, 0', and 'Fanvour's identity e^(i*pi) + 1 = 0'. Axes are labeled 'Re' and 'Im'.

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.
