Textbook for Math 31

<p>Which textbook or books do I need for Math 31B the UCLA store shows two books one required and one optional. They have the same title and author though I can only find tje optional one does that suffice or where can I get the required book? I am quite lost...</p>

<p>One is the actual textbook, the other is the solution manual. If you look up the ISBN online it should be pretty clear which is which.</p>

<p>But I did look up the books. I can’t find one of them… And the optional book seems to be the textbook…</p>
