If v is of order δ, what is the order of ∂v/∂x and ∂2v/∂x2 ?

I have never seen those symbols used before but I think I understand the problem

I believe that in this case you would have to take the differentiation power rule into account

What do you mean by "order"? Order is usually used in reference to derivatives, with dy/dx and ∂y/∂x being first-order derivatives, and with $\frac{d^2y}{dx^2}$ and $\frac{\partial^2y}{\partial x^2}$ being second-order derivatives.

$x^2 + 3x$ is a polynomial of degree two, while $t^4 - 3t^2 + 7$ is a polynomial of degree four. So what do you mean by "v is of order δ"?

What does it mean to say that a function is "of order $\delta$?

Battlemage!

What if v is a derivative? So if δ were n, v would be an nth order derivative, making the other two...

Sorry, only thing that makes any sense to me. Seems to be some sort of trick question.

Some context here from the OP would be helpful, although it's been a week since the question was posted, so we might never know.
