Calculus is about the very large/ the very small/ and how things change—the surprise is that something seemingly so abstract ends up explaining the real world. This course is a first and friendly introduction to calculus/ suitable for someone who has never seen the subject before/ or for someone who has seen some calculus but wants to review the concepts and practice applying those concepts to solve problems. One learns calculus by doing calculus/ and so this course is based around doing practice problems.
