sinê(squareMatrix1) ⇒ squareMatrix
Returns the matrix inverse sine of
squareMatrix1. This is not the same as
calculating the inverse sine 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 mode:

sinh (expression1) returns the hyperbolic sine
of the argument as an expression.
sinh (list) returns a list of the hyperbolic sines
of each element of list1.
