Solution to part d of problem session

Hi class-

The correct solution to part d of the problem session we worked in class today is:

eta = 1 - (1/r)^(gamma - 1)

In class, I initially wrote (1-gamma) incorrectly.

Please do spend 10 minutes working parts (c) and (d) if you haven't already gotten to the answer. This will help prepare you when you start your problem set.

Cheers,
MSS
