Written by acclaimed author and mathematician George Simmons, this revision is designed for the calculus course offered in two and four year colleges and universities. It takes an intuitive approach to calculus and focuses on the application of methods to real-world problems. Throughout the text, calculus is treated as a problem solving science of immense capability.
George Simmons was an American mathematician who worked in topology and classical analysis. He was known as the author of widely used textbooks on university mathematics.
Not planning to read this ~1000 page tome cover to cover but it was supposed to be the recommended text for MIT's single variable calculus class. From perusing ToC and sample chapters it seem to be didactically sound and well written though too chatty for my taste. Planning to refer to this mainly on the topic of finding the volumes of geometric shapes like cylinder, shell (via rotation around x, y axis) and length of curves using integration. Serge lang's book "First course in calculus" is an alternate book on this topic but it didn't cover it in much detail.
Reading this book feels like a conversation and the historical comments are a great addition as they provide the context on when and why making it so enjoyable as to you feel like you walk through the people who came up with the theories.
