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

expression
Returns the requested Taylor polynomial. The
polynomial includes non-zero terms of integer
degrees from zero through
order
in (
var
minus
point
).
taylor()
returns itself if there is no
truncated power series of this order, or if it would
require negative or fractional exponents. Use
substitution and/or temporary multiplication by a
power of
(
var
minus
point
) to determine more general
power series.
point
defaults to zero and is the expansion point.
