Suppose we are given : PV = nRT, where n and R are constants.(adsbygoogle = window.adsbygoogle || []).push({});

We are told to find the partial derivative dP/dV.

Am I allowed to do this :

P = nRT/V

Then differentiate this w.r.t. to V.

I disregarded the fact that V = 0 makes the RHS undefined.

# This question came from Princeton Review's "Cracking the GRE Math Subject Test" page 160, qns 13.

The solution given uses the above method but I do not understand why V = 0 is not taken into account.
