Hi,

I don't have any question specifically but I'm very confused on this.
In integration to find area under/above a curve, when do you integrate:
1) with respect to y
2) with respect to x
3) using x coordinates
4) using y coordinates

Thanks for your help! :)

Look at the piecemeal unit of dArea you are integrating. Is is some y dx or xdy? It is those little differential areas you are integrating.

Here is a x dy dArea.
