As per the polar coordinates, the limits of the integration is written as ∬Df(rcos(θ),rsin(θ))rdrdθ.
What is meant by polar coordinates?
In math, polar coordinates refer a pair of coordinates locating the position of a point in a plane, the first being the length of the straight line ( r ) connecting the point to the origin, and the second the angle ( θ ) made by this line with a fixed line.
Here we have the limits of integration and evaluate the integral to find the volume. for the polar coordinates.
Here we have the polar representation of a point P is the ordered pair (r,θ) where r is the distance from the origin to P and θ is the angle the ray through the origin and P makes with the positive x-axis.
Then the polar coordinates r and θ of a point (x,y) in rectangular coordinates satisfy
=> r=x² + x² and tan(θ)=yx;
Here the rectangular coordinates x and y of a point (r,θ) in polar coordinates satisfy and x=rcos(θ) and y=rsin(θ).
Then the area element dA in polar coordinates is determined by the area of a slice of an annulus and is given by dA=rdrdθ.
Here we have to convert the double integral ∬Df(x,y)dA to an iterated integral in polar coordinates,
Now, we have to substitute rcos(θ) for ,x, rsin(θ) for ,y, and rdrdθ for dA to obtain the iterated integral
=> ∬Df(rcos(θ),rsin(θ))rdrdθ.
