have you looked at the thread "should i become a mathematician" in the academic advising forum? (post #1?)

Courant and Hilbert, Methods of mathematical physics (the original two-volume version)

I strongly recommend Differential and Integral Calculus, vols 1 and 2, by Richard Courant, epecially given the current price: of about $15 each:

Notice the 2 volume set offered for $32, about half way down the page, formerly belonging to, and signed by, my friend the famous mathematician and author Ray Kunze, (now deceased).

I offer this as evidence that a mathematician would want these books.
