Find the area of the region bounded by the curve y2 = 4x and the line x = 3.
Answer :
It is given that the region bounded by parabola, y2 = 4x and the line x = 3.
From the figure we can see that the required is OACO.
We can observed that the area OACO is symmetrical about x –axis.
Thus, Area of OACO = 2(Area of OAB)
So, Area OACO 
Therefore, the required area is
