Question
Find the area enclosed between the parabola
y
2
=
z
and
x
2
=
y
.
Open in App
Solution
x
2
=
y
and
y
2
=
x
are two parabola
y
2
=
a
⇒
y
=
√
x
∴
We need to find the area enclosed between the functions
y
1
=
x
2
and
y
2
=
√
x
y
1
=
y
2
⇒
x
2

⇒

)
=

Thus intersection of the two functions occurred
x
=
0
and
x
=
!
When
x
=
(
0
,

)
the function
y
2
≥
y
1
, and that therefore the difference between the two functions is given by the function
