c3 diffrentiation help Watch
dy/dx at point (8,2) on the curve 3y^2 -2y=x
have a total metal block please help!
thanks in advance
Alternatively, you could divide by 3, then complete the square on the left hand side and try and rearrange the equation so it's in the form "y = ...".
Implicit differentiation. Does that mean anything to you?
^ if not, then make sure you can get in terms of just y
and just remember things such as
and do the differentiation from there, using c2 knowledge
^took too long typing, but people saying implicit differentiation, thats c4, or it is for edexel
no havnt heard of it...
If so, differentiate that whole equation with respect to x.
Ooh, alternatively, just differentiate with respect to y and take the reciprocal.
Implicit differentiation is Edexcel C3. I would know seeing as I just had the exam with a question about implicit diff on it.
differential yeah, the implicit isn't introduced till c4, there isn't much new in c4 its mostly applying what you already know.
didn't stop me from failing it this summer
this years c4 wasn't the worst it could have been, but it wasn't nice.
