Question

is it possible to find line element of plane polar coordinate? why?​

Answer 1

The area of a region in polar coordinates

defined by the equation

r=f(θ) with α≤θ≤β is given by the integral

A=12∫βα[f(θ)]2dθ.

To find the area between two curves in the polar coordinate system, first find the points of intersection, then subtract the corresponding areas.
