Sistem koordinat bola
caption: Sistem koordinat bola (r, θ, φ) digunakan dalam bidang fisika ( ISO 80000-2:2019 ): Jarak radial r , sudut θ ( theta ), dan sudut azimuthal φ ( phi ). Simbol ρ ( rho ) r .
caption: Spherical coordinates (r, θ, φ) as often used in mathematics : radial distance r , azimuthal angle θ , and polar angle φ . The meanings of θ and φ have been swapped compared to the physics convention.
