Synopsis

Master the language of change with a clear, practical introduction to infinitesimal calculus.

This edition explains how partial derivatives and total differentials reveal the behavior of multivariable systems, with an emphasis on applications in economics and statistics.

The book guides you from core ideas to real‑world techniques. It discusses the geometry of tangent planes, the meaning of slopes in multiple directions, and how to differentiate when variables depend on one another. Through worked examples and clear explanations, you’ll see how calculus helps model and analyze complex relationships.
  • Learn how to express changes in multiple variables using total and partial derivatives.
  • Understand the concept of a differential and its use in solving implicit relationships.
  • See practical applications in economic theory and statistical modeling.
  • Develop the ability to interpret and apply calculus concepts without heavy abstraction.
Ideal for readers seeking a solid, hands‑on foundation in calculus and its applications to economics and statistics.
