cosh()
Catalog
>
cosh(Va l u e 1) ⇒ value
cosh(List1) ⇒ list
cosh(Va l ue 1 ) returns the hyperbolic cosine of the argument.
cosh(List1) returns a list of the hyperbolic cosines of each element of
List1.
cosh(squareMatrix1) ⇒ squareMatrix
Returns the matrix hyperbolic cosine of squareMatrix1. This is not
the same as calculating the hyperbolic cosine 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:

Catalog
>
cosh/(Va lu e1 ) ⇒ value
cosh/(List1) ⇒ list
cosh/(Va l ue 1 ) returns the inverse hyperbolic cosine of the
argument.
cosh/(List1) returns a list of the inverse hyperbolic cosines of each
element of List1.
Note: You can insert this function from the keyboard by typing
arccosh(...).
cosh/(squareMatrix1) ⇒ squareMatrix
Returns the matrix inverse hyperbolic cosine of squareMatrix1. This
is not the same as calculating the inverse hyperbolic cosine 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 and In Rectangular Complex Format:
To see the entire result, press £ and then use ¡ and ¢ to
move the cursor.
cot()
μ key
cot(Va lu e 1) ⇒ value
cot(List1) ⇒ list
Returns the cotangent of Va lu e 1 or returns a list of the cotangents of
all elements in List1.
Note: The argument is interpreted as a degree, gradian or radian
angle, according to the current angle mode setting. You can use ¡,
G
,
or R to override the angle mode temporarily.
In Degree angle mode:
