Abstract

In discussing the area of ​​the field, we will use two coordinate systems, namely the Cartesian Upright Coordinate (Coordinate Elbow) and the Polar Coordinate. Area of ​​the Cartesian Upright Coordinate There are four kinds: (1). The area of ​​the area passed by the curve y = ƒ (x) > 0, the x-axis, the line x = a and the open x = b, (2). The area of ​​the area passed by the curve y = ƒ (x) < 0, the x-axis, the line x = a and the open x = b, (3). The width between the two curves y₁ = ƒ₁ (x) and y₂ = ƒ₂ (x); (4). The area of ​​the field passed by the curve x = ƒ (y) > 0, the y-axis, line y = c and line y = d. depending on the area of ​​the curve in the polar form r = ƒ (θ) between two radians with θ = θ₁ and θ = θ₂. In this research we will discuss the use of integral for wide field at Upright Cartesius Coordinate and at Polar Coordinate.
