Detailed Description

Spherical coordinate system parameters.

Spherical coordinates (r, θ, φ) where:

• r: radial distance from origin (r ≥ 0)
• theta: polar angle measured from +z axis (theta in [0, pi])
• phi: azimuthal angle in x-y plane (phi in [0, 2*pi])

Physical interpretation:

• x = r * sin(θ) * cos(φ)
• y = r * sin(θ) * sin(φ)
• z = r * cos(θ)

Common use cases:

• Planetary atmospheres (full sphere)
• Radial growth problems (bubble, crystal)
• Spherical shell problems (annular: r_min > 0)
