sinh() MATH/Hyperbolic menu
sinh( expression1 ) ⇒ expression
sinh( list1 ) ⇒ list
sinh ( expression1 ) returns the hyperbolic sine of
the argument as an expression.
sinh ( list ) returns a list of the hyperbolic sines of
each element of
list1 .
sinh(1.2) ¸ 1.509...
sinh({0,1.2,3.}) ¸
{0 1.509
... 10.017...}
sinh( squareMatrix1 ) ⇒ squareMatrix
Returns the matrix hyperbolic sine of
squareMatrix1 . This is not the same as calculating
the hyperbolic sine of each element. For
information about the calculation method, refer
to
cos().
squareMatrix1 must be diagonalizable. The result
always contains floating-point numbers.

sinhê ( expression1 ) ⇒ expression
sinhê ( list1 ) ⇒ list
sinhê ( expression1 ) returns the inverse hyperbolic
sine of the argument as an expression.
sinhê ( list1 ) returns a list of the inverse
hyperbolic sines of each element of
list1 .
