Homework Statement
This is an example taken from the textbook lesson and there's one part I don't understand:
Find the area of the region bounded above by the spiral
r = pi/(3θ)
and below by the polar axis, between r = 1 and r = 2.
SOLUTION:
Double integral of r(dθ)(dr) with boundaries: r:[1,2] and θ:[0,pi/(3r)]
I don't understand why the inside integral (dθ) is taken from 0 -> pi/(3r) instead of just 0->pi/3 which is what I thought it should be.
