Question

the formula of area in polar coordinates is??

Answer 1

Answer:

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.
