1. The problem statement, all variables and given/known data 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] 2. Relevant equations integral of del cross v dot da 3. 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?
