Step-by-step explanation:

Assuming that we want to find the derivative with respect to

x

of

x

y

2

(assumong that

y

is a function of

x

:

First use the product rule:

d

d

x

(

x

y

2

)

=

d

d

x

(

x

)

y

2

+

x

d

d

x

(

y

2

)

Now for

d

d

x

(

y

2

)

we'll need the power and chain rules.

d

d

x

(

x

y

2

)

=

1

y

2

+

x

[

2

y

d

y

d

x

]

d

d

x

(

x

y

2

)

=

y

2

+

2

x

y

d

y

d

x

If you want to differentiate the expression with respect to

t

then the derivatives above are all

d

d

t

and

d

x

d

t

may not be

1

.

d

d

t

(

x

y

2

)

=

y

2

d

x

d

t

+

2

x

y

d

y

d

t

If you want the partial derivatives of the function

f

(

x

,

y

)

=

x

y

2

that has been answered in another answer.
