sin( squareMatrix1 ) ⇒
⇒⇒
⇒ 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.

sinê (
expression1 ) returns the angle whose sine is
expression1 as an expression.
sinê ( 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:
sinê (1) ¸ 90
In Gradian angle mode:
sinê (1) ¸ 100
In Radian angle mode:
sinê ({0,.2,.5}) ¸

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
