WebVideo transcript. - [Voiceover] So here I'd like to talk about what the gradient means in the context of the graph of a function. So in the last video, I defined the gradient, but let me just take a function here. And the one that I had graphed is x-squared plus y-squared, f of x, y, equals x-squared plus y-squared. WebMay 22, 2024 · The symbol ∇ with the gradient term is introduced as a general vector operator, termed the del operator: ∇ = i x ∂ ∂ x + i y ∂ ∂ y + i z ∂ ∂ z. By itself the del operator is meaningless, but when it premultiplies a scalar function, the gradient operation is defined. We will soon see that the dot and cross products between the ...
