Question

prove that Vector A cross Vector A equal to Zero ​

Answer 1

Answer:

cross product ( A x B) gives a vector which is perpendicular to the plane generated by A and B. So this vector is perpendicular to A and B. For dot product of two perpendicular vector result is 0 as cos 90 = 0.

Answer 2

cross product ( A x B) gives a vector which is perpendicular to the plane generated by A and B.

So this vector is perpendicular to A and B.

For dot product of two perpendicular vector result is 0 as cos 90 = 0.
