<br>I have both the required books for Math 51: <br> <br>Vector Calculus by Colley (3rd ed) <br>Linear Algebra by Levandosky <br> <br>These books are in great condition with no writing in them. They are very close to new at a great discount off the bookstore prices. Besides, the bookstore runs out of used books so quickly and has tax prices! <br>Contact me with any questions!
