sinh

Hiperbolic sine by tau approximation for rtau object.


Syntax
   f = sinh(r)

Description
   F = sinh(r) is a function to approximate by tau method sinh(r), r in 
   [a, b]. We are using schursolver function, which will decide the 
   approximation degree to achieve 1e-16.

Input
   r = rigth member in tau method (rtau object).

Output
   f = coefficients of sinh(r).
