sin
=
sin angle or sin ( expression )
Returns the sine of angle or expression, which can be
real or complex.
An angle is interpreted as degrees or radians according
to the current angle mode. In any angle mode, you can
designate an angle as degrees or radians by using the
¡
or r designator, respectively, from the MATH ANGLE
menu.
In Radian angle mode:
sin p/2 b 0
sin ( p/2) b 1
sin 45 ¡ b .707106781187
In Degree angle mode:
sin 45 b .707106781187
sin ( p/2) r b 1
The squareMatrix cannot
have repeated
eigenvalues.
sin list
Returns a list in which each element is the sine of the
corresponding element in list.
sin squareMatrix
Returns a square matrix that is the matrix sine of
squareMatrix
. The matrix sine corresponds to the result
calculated using power series or Cayley-Hamilton
Theorem techniques. This is not the same as simply
calculating the sine of each element.
In Radian angle mode:
sin {0, p/2,p} b {0 1 0}
In Degree angle mode:
sin {0,30,90} b {0 .5 1}
sin L 1
- {
sin L 1 number or sin L 1 ( expression )
Returns the arcsine of number or expression, which can
be real or complex.
sin L 1 list
Returns a list in which each element is the arcsine of the
corresponding element in list.
In Radian angle mode:
sin L1 .5 b .523598775598
sin L1 {0,.5} b
{0 .523598775598}
In Degree angle mode:
sin L1 1 b 90
