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.
