<p>I am freshman student its a kind of weird question, i was taking AMS 261 Applied Calculus III MULTIVARIABLE CALC. TEXT W/WEBASSIGN, ISBN 978-1-111-23183-5. I was confused with this webassign because i couldnt get the book of this ISBN # 978-1-111-23183-5.But Applied Calculus III MULTIVARIABLE CALC.Book without web assign is available in Amazon/half.com....Where can i get this web assign access code? thanks</p>
