A Calculus Oasis - on the sands of trigonometry

A calculus companion book for Calculus I, Ii and Iii (3D Vector Calculus). Addressed to Science/Premed majors, not math majors. Very unusual for its coverage of Calc Iii. Several chapters are designed to work also as a Liberal Arts overview of calculus, although in general the book is more technical and practical than philosophical.
