The dP/dn formula in the Extra Credits section says
(d/dn)(nRT)/V = (RT/V)*(dn/d)n
while the dT/dP formula says
(d/dP){(PV)/(nR)} = {V/(nR)} * (d/dP)P
Notice that, on the right side of the equation, the dP/dn formula inverts (d/dn) while the dT/dP does not invert (d/dP). Is the first formula wrong?
