## Trigonometry in Indian Temple Architecture
*   An exploration of the geometry of the divine: fractals, grids, and the golden ratio.

## Mathematical Foundations
*   Design principles rooted in Silpa Shastras from the Gupta era.
*   Integration of angles, grids, and circles to represent cosmic order.

## Vastu Purusha Mandala
*   Blueprint based on an 8×8 grid (Bhekapada or Ajira).
*   Intersection of the square (distinct universe) and circle (infinite cosmic principle).

## Trigonometry of the Circle & Square
*   Cruciform shapes determined using side lengths relative to radii via Pi.
*   Concentric layers (Padas) from Brahma (center) to Paishachika (periphery).
*   Use of 45° angles for precise axial alignment.

## Fractal Geometry & Recursion
*   Self-repeating motifs seen in temples like Virupaksha.
*   Iterative scaling and triangular domes echoing mountain shapes.

## The Golden Ratio
*   Temple towers often approximate ϕ ≈ 1.618, mirroring the natural Fibonacci sequence.

## Numerical Symbolism
*   Data on architectural element counts:
    *   **Modhera Sun Temple:** 52 pillars (weeks) and 365 carved elephants (days).
    *   **Ranakpur Jain Temple:** 1,444 marble pillars forming a fractal network.

## Case Study: Modhera Sun Temple
*   Built for the Sun God Surya.
*   Angular divisions ensure specific solar alignment during equinoxes.

## Case Study: Ranakpur Jain Temple
*   Trigonometric layout ensures sightlines from every corner to the central idol.
*   Maintains perfect structural symmetry with 1,444 unique pillars.

## Conclusion
*   A legacy of empirical mastery in ancient engineering and mathematical application.
