As it says in title: Partial Differential Equations Walter A. Strauss Math 131P book

This is the 1st edition book, not the current edition, almost the same as current edition. The current edition has corrections, different problems, slightly different order and some additions here and there, but it should work well. It is in very good condition, no marks/highliting.

$200 new at bookstore (no used copies when I checked) and $100 to rent.

Selling for $75 obo, I'll be surprised if someone is willing to pay the $75 so make offers (though I won't go too low, since I get another chance to sell next quarter).
