I know this question is in Vector Calculus but there doesn't seem to be place where I can ask this question here. I would love it if someone could help me out. What is the square of a gradient of a function?

The gradient of a scalar function, to be more specific.

I never heard of the square of a gradient of a function. Are you asking about the Laplace operator ?

How do you solve ((grad(f(x)))^2? Im sorry. I should have written the problem.

The delta symbol you made is the gradient, right? I know there is different notations but I just want to be sure.
