Hi there, everyone! I'm sure this question has been asked many times before, but I did not really find any similar posts, so I hope you guys will bear with me! I am teaching myself what could be categorized as Calculus 1, using Adams' "Calculus: A Complete Course" along with "Schaum's 3000 Solved Problems in Calculus" and The Great Courses' "Understanding Calculus - Problems, Solutions, And Tips". I am beginning to become very passionate about mathematics, although I want to study engineering. I am really, really missing a "book of problems" of calculus 1 with applications for engineers, and I wondered if you had any suggestions? They should include answers (and preferably solutions). For me, the greatest motivation in mathematics are challenging, but still-possible-to-solve, problems, and I find mathematics to be highly interesting when I can apply what I learn. I would really, really appreciate your input here!
