2. get from you must use to evaluate and

*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??
