The hyperbolic functions are similar to the trigonometric functions, often called circular functions, in that they play an important role in problems in mathematics and the mathematics of physics. The hyperbolic functions are involved in mathematical...

The inverse hyperbolic functions are simply the inverse of the different hyperbolic functions cosh x, coth x, csch x, sech x, sinh x, and tanh x. The inverse of a function is that function reflected about the line y = x and usually denoted by f-1(x)....

In mathematics, the hyperbolic functions are analogs of the ordinary trigonometric, or circular, functions. The basic hyperbolic functions are the hyperbolic sine "sinh", and the hyperbolic cosine "cosh", from which are derived the hyperbolic tangent...

Newspapers tend to be cheerleaders in America's wars, at least in the early going. So it is not surprising that our patriotic fervor has been aroused by the newest call to arms: the War on Drugs. It has been properly declared by the president,...
