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:
