returns the hyperbolic sine of the
argument as an expression.
sinh (

returns a list of the hyperbolic sines of
each element of
list1
.

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.
