squareMatrix
Returns the matrix sine of
squareMatrix1
. This is
not
the same as calculating the 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:

as an expression.
sin
ê (
list1

returns a list of the inverse sines 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 Degree angle mode:
