tanh()
Catalog >
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.
tanh¹()
Catalog >
tanh¹(Value1) value
tanh¹(List1) list
tanh¹(Value1) returns the inverse
hyperbolic tangent of the argument.
tanh¹(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(...).

tCdf()
Catalog >
tCdf(lowBound,upBound,df) number if
lowBound and upBound are numbers, list if
lowBound and upBound are lists
Computes the Student-t distribution
probability between lowBound and upBound
for the specified degrees of freedom df.
