🔍 Sample Topic: Gradient Vector & Level Curves

Let f(x,y)=x2+y2f(x, y) = x^2 + y^2f(x,y)=x2+y2

Then, the gradient vector is:

This points perpendicularly to level curves, which are circles in this case — useful in optimization problems and understanding physical gradients (like temperature or elevation).
