“hyperbolic functions”的概念、定义、习题解题方法及翻译-物理辞典

单词	hyperbolic functions
释义	hyperbolic functions A set of functions; sinh , cosh , and tanh , that have similar properties to trigonometric functions but are related to the hyperbola in the manner that trigonometric functions are related to the circle. The hyperbolic sine (sinh) of the angle x is defined by: sinhx = 1/2(e^x - e^-x). Similarly , coshx = 1/2(e^x + e^-x) tanhx = (e^x - e^-x)/(e^x + e^-x) Hyperbolic secant (sech), cosecant (cosech), and cotangent (coth) are the reciprocals of cosh, sinh, and tanh, respectively
