Determine the Absolute value of a Vector
Following procedures show you how to determine the absolute value
(size) of a vector:
Example: To determine the absolute value of the Vector C. As Vector
C = (4,5,-6) and already created in the calculator.
Operation
Example: Base on Vector A=(–1, –2, 0) and Vector B=(1, 0, –1),
determine the size of the angle (angle unit: Deg) and the
size 1 vector perpendicular to both A and B.
Size 1 vector perpendicular to both A and B=
VctA x VctB
Result:
|VctA x VctB|
Operation
