A practical book for learning calculus through phenomena. I bought this used for use a few times in university, and am now selling it as I no longer need it. It shows considerable signs of use, but there is no writing inside. There is a scratch on the bottom corner of the book, as shown in the third photo. There are some stains in photos 4 and 5. - Title: Let's Learn Calculus from Phenomena - Publisher: Nihon Hyoronsha Please understand that this is a used item. Thank you for looking! ☺︎
