Hyperbolic Functions: with Configuration Theorems and Equivalent and Equidecomposable Figures (Dover Books on Mathematics)

This single-volume compilation of three books centers on Hyperbolic Functions, an introduction to the relationship between the hyperbolic sine, cosine, and tangent, and the geometric properties of the hyperbola. Configuration Theorems concerns theories on collinear points and concurrent lines, and Equivalent and Equidecomposable Figures examines the dissection and reassembly of polyhedrons. 1963 edition.
