This is a textbook I used in university. It has some folds and scratches, but there's almost no writing in it. It should be fine for use in university, etc. No returns accepted. - Title: Practical Calculus for Science and Engineering Students - Price: 1900 yen - Authors: Naoki Yamada, Mamoru Yoshida, Yukio Fukuzaki, Naoto Tanaka - Publisher: Gakushu Tosho Publishing Thank you for looking.
