<p>Hi there! I too am a new member of the class of 2014 and might see you in Maths 230 in the fall!</p>
<p>I don’t know Maths 230 all that well of course, but one thing I might recommend is some linear algebra. Just take a look in your library to see if there are any linear algebra books. Also, by Spivak I assume you mean his ‘Calculus’ rather than his ‘Calculus on Manifolds’ - you might also want to take a look at a non-rigourous text to get an feel for multivariable calculus…</p>
<p>In terms of other textbook recommendations, take a look here: [url=<a href=“http://www.math.yale.edu/public_html/USM/textbooks.html]Textbook”>http://www.math.yale.edu/public_html/USM/textbooks.html]Textbook</a> Information<a href=“it’s%20a%20list%20of%20all%20the%20maths%20texts%20Yale%20uses,%20so%20that%20might%20give%20some%20indication”>/url</a></p>
