This provides a minimum of 25% longer life than "fixed" rod bushing design. It also reduces breakaway and running friction, which improves overall actuation responsiveness. Cylinders can be customized to fit any application.

### Hyperbolic functions - sinh, cosh, tanh, coth, sech, csch

INVERSE HYPERBOLIC FUNCTIONS. If x = sinh y, then y = sinh-1 a is called the inverse hyperbolic sine of x. Similarly we define the other inverse hyperbolic functions. The inverse hyperbolic functions are multiple-valued and as in the case of inverse trigonometric functions we restrict ourselves to principal values for which they can be considered as single-valued.
