returns the hyperbolic cosine
of the argument as an expression.
cosh (

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

squareMatrix
Returns the matrix hyperbolic cosine of
squareMatrix1
. This is not the same as calculating
the hyperbolic cosine of each element. For
information about the calculation method, refer
to
cos()
.
squareMatrix1 must be diagonalizable. The result
always contains floating-point numbers.
