In mathematics, hyperbolic functions are analogues of the ordinary trigonometric functions, but defined using the hyperbola rather than the circle. Just as the points (cos t, sin t) form a circle …
双曲函数(Hyperbolic functions) - 知乎 - 知乎专栏
三角函数有反三角函数,就是三角函数的逆函数,双曲函数也有,下面是sinh、cosh、tanh的反函数图像: 并且我们是可以求出各个反双曲函数的对数表示式的: 这些是怎么算出来的? 其实 …
