Multivariable Calculus with Applications [Lax] - mklabgr - 09-03-2026
Multivariable Calculus with Applications
Book:Multivariable Calculus with Applications
Authors: Peter D. Lax and Maria Shea Terrell
Publication date: 2018
Publisher: Springer, Cham
Series:Undergraduate Texts in Mathematics
Summary
Multivariable Calculus with Applications develops the calculus of functions of several variables while continually connecting the subject to the familiar ideas of one-variable calculus. Beginning with vectors, matrices, and functions of several variables, Lax and Terrell introduce differentiation, partial derivatives, tangent planes, inverse functions, and higher-dimensional versions of the derivative. Rather than treating these ideas merely as computational techniques, the authors emphasize their geometric meaning and the mathematical principles underlying them.
The second half of the book develops multiple integration, line and surface integrals, vector calculus, and the major integral theorems, including the divergence theorem and Stokes' theorem. These results are presented as natural generalizations of the Fundamental Theorem of Calculus. A particularly distinctive feature is the strong connection with physics: motion, vector fields, flux, conservation laws and physical phenomena are used to motivate the mathematics. The final chapter goes further than many standard Calculus III textbooks by introducing partial differential equations, showing how vector calculus provides the mathematical language for fundamental physical theories.
The book combines mathematical precision with an unusually application-oriented presentation. It contains roughly 500 exercises and more than 200 illustrations, with problems ranging from straightforward practice to more demanding theoretical questions. Reviewers have particularly praised its pedagogical presentation and its ability to maintain mathematical rigor without making the exposition unnecessarily formal. It is therefore suitable not only for mathematics students but also for students of physics and engineering who want to understand why multivariable calculus works rather than merely learn computational formulas.
Main topics
- Vectors and matrices
- Functions of several variables
- Partial and total differentiation
- Tangent planes and inverse functions
- Applications of differentiation to motion
- Double and multiple integrals
- Line and surface integrals
- Vector fields
- Divergence theorem
- Stokes' theorem
- Conservation laws
- Partial differential equations
Key takeaways
- Conceptual rather than purely computational: the authors repeatedly relate multivariable concepts to their one-variable analogues.
- Strong connection with physics: vector calculus, conservation laws and PDEs show why the theory matters in science.
- More advanced than a routine Calculus III text: it introduces substantial mathematical structure while remaining accessible to students who know ordinary single-variable calculus.
- Excellent for self-study: the large collection of exercises and extensive illustrations make it particularly useful for motivated mathematics and STEM students.
