Mirror Math: Holographic Trigonometry Trigonometry is not just math—it’s the language of light. In Quantum Information Holography (QIH), every triangle, every sine and cosine function, is really a projection of spinning light—no pencil needed. The tip of a Quantum State Vector, or QSV, is like a light clock—spinning at the speed of light. Its projection onto the x-axis is cosine of theta, written as: cos(θ) That’s the horizontal velocity of light. Its projection onto the y-axis is sine of theta,
