Explanation Given: ( x a ) 2 + ( y b ) 2 = 1 Let, the x -coordinate be ' 0 ' . For the y -coordinate, we integrate between the two points where it crosses the x -coordinate. Then we divide by the area. Now, the area of the ellipse is the product of the value of π , major axis and minor axis. When, y = 0 , ( x a ) 2 + ( 0 b ) 2 = 1 ( x a ) 2 = 1 x = a When, x = 0 , ( 0 a ) 2 + ( y b ) 2 = 1 y = b Therefore, major and minor axis of the ellipse is b and a respectively. Area of the ellipse, = π × ( b × a ) = π a b Area of the half ellipse, = 1 2 π a b Now, ( x a ) 2 + ( y b ) 2 = 1 ( y b ) 2 = 1 − ( x a ) 2 y 2 = b 2 ( 1 − x a 2 2 ) On integration, we ge ∫ y 2 d x = ∫ − a a b 2
