Hi, I'm nearly finished with calc III ala Thomas Calculus. I'm really just clearing up any stray concepts and was thinking of getting the Dover book Ordinary Differential Equations by Tenenbaum/Pollard. I'm wondering would the book be a giant leap? https://www.amazon.com/Ordinary-Differential-Equations-Morris-Tenenbaum/dp/0486649407/ref=pd_sim_b_7 The books looks, to me, easy enough if you have a rock solid understanding of calculus but I'd like a few second opinions on that. I'm currently studying physics and I think this book would aid me in getting more advanced texts. The main question is, would I be able to handle this book based on the knowledge books like Thomas Calculus & University Physics (Young) impart?
