matrix
Solves multiple systems of linear equations,
where each system has the same equation
coefficients but different constants.
Each column in
constMatrix
must contain the
constants for a system of equations. Each column
in the resulting matrix contains the solution for
the corresponding system.

returns the sine of the argument
as an expression.
sin(
list1
)
returns a list of the sines of all elements
in
list1
.
Note:
The argument is interpreted as a degree,
gradian or radian angle, according to the current
angle mode. You can use

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.
