In this book, we cover the basics of a first and second-semester course in the calculus of a single variable. Topics include limits and continuous functions, derivatives and their applications, and integrals and their applications. Techniques of integration and then infinite sequences and series are detailed. While we're learning calculus we'll also be learning the python programming language. We'll study calculus numerically, symbolically, and graphically. This three-prong approach allows us to engage in calculus, learn it faster, and explore it deeper.
