## Homework Statement

Please don't make me post the entire question. If so, can I take a picture of the example in my textbook?

I am looking at an example in my textbook where we are to check Stoke's theorem

After doing the cross-product of del cross v I get (4z^2-2x)[x hat] + (2z^2)[z hat]

since da points in the x direction

da =dydz[x hat]

## Homework Equations

integral of del cross v dot da

## The Attempt at a Solution

when they do the integral, it is of the x component alone. why? is it because da is pointing in the x direction?
