1. xy-2=0Hi everyone!
Find dy/dx
1. xy-2=0
2.x/y+4x=1
3.x^2y^3+xy^2-8=0
1) Since y = 2/x, we have y' = -2/x^2.Hi everyone!

Oh yeah it was implicit. Shit my bad :/1) Since y = 2/x, we have y' = -2/x^2.
2) Note y = x/(1-4x). Now we can use the quotient rule to get y' .

Could you use it in 3U?Implicit differentiation is only part of the HSC 4U syllabus.
Yeah (pretty sure)Could you use it in 3U?
You use implicit in conics to derive equations of tangents and normals to hyperbolas or ellipses.I'm pree sure implicit is part of 3U, you use it in 4U for conics (apparently you do)
It's not mentioned in the 3U syllabus, but you can still use it and I'm pretty sure most teachers teach it.I'm pree sure implicit is part of 3U, you use it in 4U for conics (apparently you do)
It's really powerful and simple.It's not mentioned in the 3U syllabus, but you can still use it and I'm pretty sure most teachers teach it.
What rule is this?It's really powerful and simple.
How about the Square Root Function Rule?
It's where if you differentiate a square root function, it'sWhat rule is this?
What I meant was that could I just write that immediately without showing working out?That's an application of the chain rule.
Pretty sure you are allowed to use the chain rule by inspection, aren't you (depends on the question maybe)? You can write "chain rule" in brackets as a reason.What I meant was that could I just write that immediately without showing working out?

What is it? I've never heard of this before in 3U. Can somebody plz teach me/link me a resource to learn it?It's really powerful and simple.

huehuehuehueIt's where if you differentiate a square root function, it's
(u')/2*sqrt*f(u)
yeah I did that many times and my teacher said it was okay. Youre using substitution technicallyThat's an application of the chain rule.
google is a startWhat is it? I've never heard of this before in 3U. Can somebody plz teach me/link me a resource to learn it?
