Best ResponseYou've already chosen the best response.1If all you want is the direction of the gradient, you can factor out any common value. (or, often it's nice to normalize the gradient vector to unit length ) However, they make a mistake by not using <2,4,4> to calculate the actual change in w as you move a specific distance and direction. For this problem, you must use the correct magnitude and direction of the gradient.
