WebThe gradient is a fancy word for derivative, or the rate of change of a function. It’s a vector (a direction to move) that. Points in the direction of greatest increase of a function … WebOct 2, 2024 · And there we have it, the gradient is aligned with the direction perpendicular to the orange line and so, it changes z the most. It turns out that going along the gradient increases z the most while going in the opposite direction to it (note that both these directions are orthogonal to the orange line) decreases z the most.
