Cross Product of two Vectors

Let’s start this section off along with a quick discussion on what vectors are used for. That are used to represent quantities in which have both a magnitude and a direction. Excellent instances of quantities in which can be represented by vectors are force and velocity. Both of these have a track and a enormity.

Let’s consider force for a second. A force of say 5 Newtons in which is applied in a particular direction could be applied at any point in space. Instead, the point whereas we apply the force does not change the force itself. Forces are free of the point of application. To describe a force all we require to know is the magnitude of the force and the direction in which the force is applied in.

The similar idea carries more commonly along with vectors. Vectors just a impart magnitude and direction. They do not inform any information about where the quantity is applied. This is a significant idea to always notice in the study of vectors.

In a graphical sense vectors are reprised through directed line segments. A length of the line segment is the magnitude of the vector and the direction of the line segment is the direction of the vector. 

Therefore, because vectors don’t inform any information about whereas the quantity is applied any intended for line segment along with the similar length and direction will represent the similar vector.
