180 Alphabetical Listing
tangentLine()
Catalog >
Make sure that the independent variable is
not defined. For example, If f1(x):=5 and
x:=3, then tangentLine(f1(x),x,2) returns
“false.”
tanh()
Catalog >
tanh(Expr1) ⇒ expression
tanh(List1) ⇒ list
tanh(Expr1) returns the hyperbolic tangent
of the argument as an expression.
tanh(List1) returns a list of the hyperbolic
tangents of each element of List1.
tanh(squareMatrix1) ⇒ 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.
In Radian angle mode:
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
In Radian angle mode and Rectangular
complex format:
