Silindirik ve küresel koordinatlarda del

Bu liste eğrisel koordinat sistemleri ile çalışılırken genel olarak kullanılan vektör hesabı formüllerinin bir listesidir.

Not

• Bu sayfada standart fizik gösterim kullanır. küresel koordinatlar için, θ açısı yarıçap vektörünün z ekseni ile olan açısıdır ve Söz konusu noktaya orijinden bağlanır. ϕ açısı yarıçap vektörünün x-y yüzeyine izdüşümü ile ve x ekseni ile olan açıdır. Bazı kaynaklar θ ve ϕ yi ters tanıtırlar, bu anlam bağlamında böyle bir bağlantı kurulmamalıdır.
• atan2(y, x) fonsiyonu kendi etki ve görüntü nedeniyle matematiksel fonksiyon arctan(y/x) yerine kullanılabilir, klasik arctan(y/x) görüntüsü (-π/2, +π/2)aralığında idi, buradaki atan2(y, x) (-π, π] aralığındadır. (Küresel koordinatlarda Del için ifadelerin düzeltilmesi gerekebilir)
• Dönüşümler kartezyen koordinatlardan silindirik ve küreseledir.
