Excerpt from Tables of Sines, Cosines, Tangents, Cosecants, Secants and Cotangents of Real and Complex Hyperbolic Angles Hyperbolic functions are of great importance in the engineer ing theory of alternating-current lines; because they enable short and simple formulas to replace long, tedious and unwieldy computations. Nevertheless, the use of vector hyperbolic func tions in relation to telegraphic, telephonic, or power-transmission circuits has been retarded by the absence of tables of such functions.* Most of the engineer's formulas of circular trigono metry, in relation to surveying, are brief and easily remem bered; but in the absence of the customary tables of circular sines, cosines and tangents, they would have little utility.
