Elemen Differensial Panjang, Luas, Volume Pertemuan ke-4

2
Sistem koordinat Cartesian P 1 (x, y, z) P 2 (x + x, y + y, z + z) Panjang differensial dl d l = dx a x + dy a y + dz a z Luas differensial ds x = dy dz a x ds y = dx dz a y ds z = dx dy a z Volume differensial dv = dx dy dz

3
Sistem koordinat silinder P 1 ( , , z) P 2 ( + , + , z + z) Panjang differensial d l d l = d a + d a + dz a z Luas differensial ds = d dz a ds = d dz a ds z = d d a z Volume differensial dv = d d dz

4
Sistem koordinat bola P 1 (r, , ) P 2 (r + r, + , + ) Panjang differensial d l d l = dr a r + r d a + r sin d a Luas differensial ds r = r 2 sin d d a r ds = r sin dr d a ds = r dr d a Volume differensial dv = r 2 sin dr d d
