4u integration vs 3u (1 Viewer)

[wahbetemaujkardi]

Haven't done a lot of 3u integration only 4u, is that smthg to worry about? In the context that I have two tests in 2 days which both have integration except one for 4u and one for 3u

4u integration makes 3u integration look like a joke. If you've mastered 4u integration, 3u integration is pretty much free marks. Just know the basics of volumes such as the formula and everything else is just routine.

Speaking of volumes the formula for the volume of the cone is key also the axis that is rotated on is the height and the axis perpendicular to it is the radius.
End goal
h=Axis of rotation written as dx or dy
r=radius of the opposite of the rotated axis.
