I'm following L Tu's book. I am confused by the notion of smoothness. I have two questions, (1) Why does smoothness captured by infinitly differentable, if we have k times differentiable function, does that mean it is less smooth than the k+10 differentiable function? But in what way is less smooth? (2) Why do we need a smooth vector field, what if it is not smooth vector field, what smoothness can do for us in the notion of vector field.

Why smooth vector field, not non smooth ones?
