Hyperbolic Functions (Classic Reprint)

Get practical access to the hyperbolic functions that power physics, engineering, and geophysical math.

This volume presents definitions, formulas, and a wide set of tables to simplify computation in real-world applications. From the basics to advanced tables, it ties together theory and useful numerical data in one precise reference.

Compiled under the Smithsonian imprint, this edition explains how hyperbolic functions relate to circular functions and to a range of physical phenomena. It covers the foundational definitions, interpolation methods, and significant numerical constants that researchers rely on when modeling decay, projections, and mechanical strains. The text includes historical context and a clear presentation of how to use the tables for accurate calculations.

• Definitions and formulas for sinh, cosh, tanh, and related functions
• Five- and nine-digit tables for quick lookups and interpolation
• Interpolation coefficients and derivative formulas for precise results
• Conversion tools and notes on gudermannian and related measures

Ideal for readers who work with physics, geology, astronomy, or engineering and need a reliable reference for hyperbolic computations.
