Question

Find the area enclosed between the parabola y2=z and x2=y.

Open in App
Solution

x2=y and y2=x are two parabola
y2=a y=x
We need to find the area enclosed between the functions
y1=x2 and y2=x
y1=y2x2=x12x2x12=0x12(x121)=0
Thus intersection of the two functions occurred x=0 and x=!
When x=(0,10) the function y2y1, and that therefore the difference between the two functions is given by the function 2IR where z=x12x2
z=zdz=23x3213x3+C
10zdz=23(1)32(13)(1)3+c23(0)23(13)(0)
=2313+C0+0C=13
The area enclosed between the parabola x2=y and y2=x is 13.
