How to prove that δf(x₀,y₀,z₀) · γ'(t_0) = 0 given f(x, y,z) = x² + 4y² + 9z² and γ(t) = (x(t), y(t), z(t)) wich images is a part of the level surface x² + 4y² + 9y² = 1? (consider δf as the gradient, brain. ly does not have nabla)

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.

hope this !
