Spherical gradient
• This article uses the standard notation ISO 80000-2, which supersedes ISO 31-11, for spherical coordinates (other sources may reverse the definitions of θ and φ): • The function atan2(y, x) can be used instead of the mathematical function arctan(y/x) owing to its domain and image. The classical arctan function has an image of (−π/2, +π/2), whereas atan2 is defined to have an image of (−π, π]. WebVectors are defined in spherical coordinates by ( r, θ, φ ), where. r is the length of the vector, θ is the angle between the positive Z-axis and the vector in question (0 ≤ θ ≤ π ), and. φ is the angle between the projection of the …
