This is an extract of our Finals document, which we sell as part of our Calculus III Notes collection written by the top tier of Nanyang Technological University students.

The following is a more accessble plain text extract of the PDF sample above, taken from our Calculus III Notes. Due to the challenges of extracting text from PDFs, it will have odd formatting:

Polar coodrinates:

r, th are dened as:

x = r cos th, y = r sin th
r2 = x2 + y 2 , r = r cos2 th + r sin2 th
dA = r * drdth

Finally where

[?][?]

f (x, y)dxdy =
D

[?][?]

r * f (r cos th, r sin th) drdth
E

E is the same region in r, th.

Cylindrical coordinates:

r, th, z are dened as:

x = r cos th, y = r sin th, z = z r2 = r2 cos2 th + r2 sin2 th
dV = rdr dthdz

Finally

where

[?][?][?]

f (x, y, z)dxdydz =

V [?][?][?]

r * f (r cos th, r sin th, y) drdthdz
W

W is the same region in cylindrical coordinates.
