Three compact, self-contained handbooks from a well-known Soviet series aimed at bridging gaps between standard university mathematics courses and the practical needs of working engineers and technical students. Yanpolsky's volume on hyperbolic functions offers a systematic treatment of the hyperbolic and inverse hyperbolic functions, their relations to trigonometric and logarithmic functions, and their applications to integration and differential equations, supported by extensive tables and worked problems drawn from physics and engineering. Merkin's monograph develops the algebra of free and sliding (line-bound) vectors, including the theory of reducing systems of sliding vectors to their simplest equivalent form — material of direct relevance to statics and rigid-body mechanics. Goldfain's volume, edited by Rudolf Guter, presents vector analysis and field theory for an engineering readership, covering gradient, divergence, curl, and the classical integral theorems with an emphasis on physical applications including wave equations. Together the three volumes typify the extensive Soviet tradition of accessible, rigorously written mathematical handbooks produced for the country's engineering education system, and remain useful reference texts for their subjects even today.
