using floating-point arithmetic.
• If Tol is omitted or not used, the default
tolerance is calculated as:
5E−14 •max(dim(coeffMatrix))
•rowNorm(coeffMatrix)
simult(coeffMatrix, constMatrix[, Tol]) ⇒
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.
Solve:
x + 2y = 1
3x + 4y = −1
x + 2y = 2
3x + 4y = −3
For the first system, x=−3 and y=2. For the
second system, x=−7 and y=9/2.
sin()
µ key
sin(Value1) ⇒ value
sin(List1) ⇒ list
sin(Value1) returns the sine of the
argument.
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°,
g
,
or
r
to override the angle mode setting
temporarily.
In Degree angle mode:
In Gradian angle mode:
In Radian angle mode:
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().
In Radian angle mode:
