I know that you determine maximum value of a directional derivative at a point by finding...
[tex]
|\nabla f(a_0 ,b_0 )|
[/tex]
But how do you find the minimum value?
I'm also kinda wondering exactly what a gradient is. It seems like if you have the gradient equation and a point... all you are getting is a single vector and a single rate of change... doesn't seem all that useful.
