This text serves as a concise introduction to the ocean of information collectively known as “Engineering Mathematics.” Admittedly, compiling everything into a short book that is useful to any audience is an impossible task; therefore, we picked a few main ideas holding up the mathematics within the engineering curriculum instead of stuffing all of the details into such a small package. This text addresses conceptual understanding as often as possible by providing an intuitive basis for formalized study within engineering/mathematics. Whether you are a math or science instructor tasked to teach an engineering class, a high school student looking into engineering, or an engineering student already, we hope you are able to walk away from this text with tangible outcomes—maybe even a refined perspective on the subject.
