Absolute value function
The absolute value function (ABS), when applied to a vector, produces the
magnitude of the vector. For a vector A = [A
magnitude of the vector. For a vector A = [A
1
,A
2
,…,A
n
], the magnitude is
defined as
. In the ALG mode, enter the function
name followed by the vector argument. For example:
BS([1,-2,6]),
BS( ), BS(u3), will show in the screen as follows:
The MTH/VECTOR menu
The MTH menu (

vector objects:
The VECTOR menu contains the following functions (system flag 117 set to

Magnitude
The magnitude of a vector, as discussed earlier, can be found with function
ABS. This function is also available from the keyboard (
