tan⁻¹()
µ key
Returns the matrix inverse tangent of
squareMatrix1. This is not the same as
calculating the inverse tangent of each
element. For information about the
calculation method, refer to cos().
squareMatrix1 must be diagonalizable. The
result always contains floating-point
numbers.
tangentLine()
Catalog >
tangentLine(Expr1,Var,Point) ⇒
expression
tangentLine(Expr1,Var=Point) ⇒
expression
Returns the tangent line to the curve
represented by Expr1 at the point specified
in Var=Point.
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.
