Q.
d.
y
=
tan
−
1
(
3
x
)
y=\sqrt{\tan ^{-1}(3 x)}
y
=
tan
−
1
(
3
x
)
Square both sides:
Square both sides to get rid of the square root.
y
2
=
tan
−
1
(
3
x
)
y^2 = \tan^{-1}(3x)
y
2
=
tan
−
1
(
3
x
)
Apply tangent function:
Now, apply the tangent function to both sides to isolate the term with
x
x
x
.
tan
(
y
2
)
=
3
x
\tan(y^2) = 3x
tan
(
y
2
)
=
3
x
Divide by
3
3
3
:
Divide both sides by
3

x = \frac{\tan(y^2)}{3}
x
=
