If gas in a cylinder is maintained at a constant temperature T, the pressure P is related to the volume by a formula of the form
\(P=\frac{nRT}{V-nb}-\frac{an^2}{V^2}\)
(a) in which a, b, n, and R are constants. Find dP/dV.
(b) Now suppose temperature is not constant and that T, P, and V are functions of time t. Find dP/dt.
(c) Describe in words the meanings of dP/dV and dP/dt.

Ответ:
This function is odd
Step-by-step explanation:
In order to find if a function is even or odd, you have to start by plugging -x in for x. If the function is exactly the same, then it is even. If it is opposite, then it is odd. This will produce an opposite function thus making it odd.
