1. Vector A=6xhat, vector B= -2yhat. find vector A x vector B. Draw the vectors

Question

1. Vector A=6xhat, vector B= -2yhat. find vector A x vector B. Draw the vectors including the resultant vector on the x, y, and z graph.

2. Vector A=6xhat, vector B= -2yhat. find vector B x vector A. Draw the vectors including the resultant vector on the x, y, and z graph.

3. Vector A= -4zhat, vector B= -3xhat. find vector A x vector B. Draw the vectors including the resultant vector on the x, y, and z graph.

4. Vector E= 5xhat. Vector A = 5xhat. What is the dot product? What id vector A = 2xhat + 3 yhat?

Explanation / Answer

follow the rules of dot and cross product.

for dot product i. i = j.j = k.k= 1

other dot product=0

for cross product ii = jXj=kXk=0

iXj=k

jXk=i

kXi=j

if we reverse the order we will have the same result but with negative sign.
