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! :)

**bobpursley**, Thursday, October 16, 2008 at 10:27amLook 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.
