sin ê ( 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:
