##### 1 Answer

You need to use implicit differentiation. Please see the explanation.

#### Explanation:

Given:

Differentiate with respect to P:

The term on the left is a product of two variables, therefore, we use the product rule:

The derivative of P with respect to P is 1:

We use the chain rule on the derivative in the second term:

Because the derivative is with respect to V, we may apply the power rule:

The derivative of the constant on the right is 0:

Solve the above equation for
