Differential geometry has a wide range of applications, going far beyond strictly mathematical pursuits to include architecture, engineering, and just about every scientific discipline. John Oprea\u27s second edition of Differential Geometry and Its Applications illuminates a wide range of ideas that can be beneficial to students majoring not only in mathematics but also in other fields. Differential Geometry and Its Applications was written to help students adapt to a type of mathematics that is a unified whole, one that mixes together geometry, calculus, linear algebra, differential equations, complex variables, the calculus of variations, and various notions from the sciences. The textbook touches on many different mathematical concept...
