cos ê( ) cosê(Value1) ⇒ value cosê(List1) ⇒ list In Degree angle mode: cosê(Value1) returns the angle whose cosine is Value1. cosê(List1) returns a list of the inverse cosines of each element of List1. Note: The result is returned as a degree, gradian or radian angle, according to the current angle mode setting. In Gradian angle mode: In Radian angle mode: /n keys cosê(squareMatrix1) ⇒ squareMatrix Returns the matrix inverse cosine of squareMatrix1. This is not the same as calculating the inverse 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 Rectangular Complex Format: £ ¡ ¢ To see the entire result, press and then use and to move the cursor. cosh( ) cosh(Value1) ⇒ value cosh(List1) ⇒ list cosh(Value1) returns the hyperbolic cosine of the argument. cosh(List1) returns a list of the hyperbolic cosines of each element of List1. cosh(squareMatrix1) ⇒ squareMatrix In Radian angle mode: 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.
