tanh⁻¹()
Catalog >
tanh⁻¹(Expr1) ⇒ expression
tanh⁻¹(List1) ⇒ list
tanh⁻¹(Expr1) returns the inverse
hyperbolic tangent of the argument as an
expression.
tanh⁻¹(List1) returns a list of the inverse
hyperbolic tangents of each element of
List1.
Note: You can insert this function from the
keyboard by typing arctanh(...).
In Rectangular complex format:
tanh⁻¹(squareMatrix1) ⇒ squareMatrix
Returns the matrix inverse hyperbolic
tangent of squareMatrix1. This is not the
same as calculating the inverse 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.

taylor()
Catalog >
taylor(Expr1, Var, Order[, Point]) ⇒
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.
