Implicit differentiation help...

Bloody C4

I need to differentiate: 6xy

I get 6(dy/dx), but that ends up giving me an incorrect final answer for the question.

I woke up at 7pm yesterday and the exam is in 7 hours, so I'm just going through exam papers now. Thanks for the help.

It's annoying when you forget the simple things, such as the product rule. :rolleyes:

I got the answer 6x(dy/dx) + 6y btw.

Anyone who isn't doing C4 or higher must be confused by this!

This is my last maths exam, a culmination of 2 years' work. CULMINATION!

Anyone else doing C4?

Did the exam this morning, it was a mix of easy and very difficult questions. I think I got the grade I needed though.
