Explanation Given: the region inside the circle, r = 2 a sin θ The region outside the circle, r = a Calculation: Area in polar coordinates- Let’s consider that r = f ( θ ) defines a polar curve, Here f is continuous f ( θ ) ≥ 0 on the closed interval α ≤ θ ≤ β , where 0 ≤ β − α ≤ 2 π Therefore the region bounded by the curve, r 1 = f 1 ( θ ) , r 2 = f 2 ( θ ) and the rays θ = α and θ = β has area A = 1 2 ∫ α β ( r 1 2 − r 2 2 ) d θ = 1 2 ∫ α β ( f 1 2 ( θ ) − f 2 2 ( θ ) ) d θ The objective is to find the region inside the circle r = 2 a sin θ and outside the circle r = a Suppose, f 1 ( x ) = 2 a sin θ and f 2 ( x ) = a are the curves of circles. First, to find the point to intersection of the two curves; Equate both equation; 2 a sin θ = a or sin θ = 1 2 which implies that the curves intersect each other at θ = π 6 , 5 π 6 Here, the curve r = 2 a sin θ is on the top in the interval [ π 6 , 5 π 6 ] and f ( θ ) ≥ 0 . It can be seen that this corresponds to angles with measures from θ = π 6 to θ = 5 π 6 . Thus, according to the method, the required area is; A = 1 2 ∫ α β ( r 1 2 − r 2 2 ) d θ = 1 2 ∫ α β ( f 1 2 ( θ ) − f 2 2 ( θ ) ) d θ A = 1 2 ∫ π 6 5 π 6 [ ( 2 a sin θ ) 2 − a 2 ] d θ

Integration means to sum the things. In mathematics, it is the branch of Calculus which is used to find the area under the curve. The operation subtraction is the inverse of addition, division is the inverse of multiplication. In the same way, integratio…

Application of Integration

In mathematics, the process of integration is used to compute complex area related problems. With the application of integration, solving area related problems, whether they are a curve, or a curve between lines, can be done easily.

Volume

In mathematics, we describe the term volume as a quantity that can express the total space that an object occupies at any point in time. Usually, volumes can only be calculated for 3-dimensional objects. By 3-dimensional or 3D objects, we mean objects th…

Area

Area refers to the amount of space a figure encloses and the number of square units that cover a shape. It is two-dimensional and is measured in square units.
