I think you can definitely use it because IMPLICIT DIFFERENTIATION = chain rule basically which is 2 unit, so why not!

I'd say it's a fair step above conceptually from applying the chain rule in a basic 2U circumstance - Like, I doubt anyone would know how to do it without being taught it explicitly. Which is why you've got to be careful - It's an atypical/extended method, and would only really be useful in a few circumstances I can think of :)

Ok, thanks very much guys. I'll be careful if I use it.

Both a friend and I were both taught Implicit differentiation at 3U tutoring. Only ever seen it being used in 1 3U paper but still. I actually thought it was a 3U technique haha. Guess I should ask my teacher to be sure.

It's a 4U technique. Your teacher knows.

From memory she's one of them that's happy with its usage in 3U.
