The cross product
This is he result of multiplyingTwo vectors and getting a vector as wn answer.
This used the sin between the two angels and an example is torque. The result of the cross product will al ats be perpendicular tj the plabe created by the two vectors
Thr dot product
This is the cosine of two vectors multiplied.This results in a scalar much like work
The RHR ( right hand rule)
Start by pointing your thumb in the direction of the first vector in the cross product.
Then place your other fingers to point in the direction of the second vector
Your palm indicates the direction of the resultant vector.
