How does the x-component of a vector field relate to the divergence?

It's weird how I've only really just remembered the convention for a positive differential to equal the change in left to right, and not right to left. It is little things like that you completely forget and neglect when studying maths. Similar to the convention of the right hand rule when describing curls.

But sir, , if we change x, , then "y" component of vector also might change, , then why isn't considered in divergence formula?

Are P and Q derivatives? I don't see why moving to the left would have the x component be negative. It can just be smaller than before. And if it was very negative moving to the right could mean it is still negative.

how about the derivative of p as x decreases ?
