***Q1***Show the direction vectors are perpendicular to each other in the Steepest Descent Method;*

that is

I know that in steepest descent, the algorithm makes zigzags.

If one vector is A and the other is B.

And the angle between them is .

In vector multiplication

Because of the answer is 0.

But how can i relate it with steepest descent??
