The area bounded by the curve y2 = 8x and x2 = 8y is

This problem is similar to Problem 2. So we’ll solve it in a similar way.


At points of intersection,


y2 = 8x


(from the other equation)


Let us solve this.



x4 = 512x


x(x3 – 512) = 0


x = 0 or x3 = 512, i.e, x = 8


So the points of intersection are (0,0) and (8,8)


Now, let’s compute the area.


If we integrate w.r.t x, we’ll have to integrate the space between the two curves from x = 0 to x = 8.


i.e.,
