#Quick question about implicit derivatives
51 messages · Page 1 of 1 (latest)
also just to double check while im here
y(x) ' = dx/dy or y(x)'= dy/dx?
I always get it confused and the research made me even more confused
Tho i think its the latter
Basically implicit differentiation relies on the chain rule
For your first question, you need to say what sin(y) is equal to, if there’s no other functions you could just say sin(y) = a constant
It’s the latter for your second question
The derivative of sin(y) is cos(y) dy/dx
Ie cos(y) y’
But if sin(y) = a constant, then dy/dx = 0 (because 0 divided by cos(y) is 0)
Assuming ofc that cos(y) isn’t 0
,w d/dx sin(y(x))
i wonder if your wolfram was differentiating sin(y) = 0, like bottle said 
your thinking is right though
to be pedantic, y(x)' isn't a notation, it's y'(x) = dy/dx
if you need help remembering, you can pretend the apostrophe is a slash, then you get y/x which is like dy/dx 
just to remember which way around
thank you guys!
whislt im here, im checking a completely different question about limits in which again
i have conflicinting answers
Would it be ok if i ask it here so i dont have to add another post ?
or should i just make another post anyway
also here is what mine was saying
aha, you are taking the partial derivative of sin(y) with respect to x
this is a different thing to the derivative, which will come up in calc III, but basically you are asking wolfram to treat sin(y) as a constant
kind of on them for calling this "implicit differentiation calculator"
but just make sure it says $\dv{x}$ and not $\frac{\partial}{\partial{x}}$
yeah im not super used to using wolfram alpha so i dont really know honestly
I usually use other apps that are more common here
fair, im not a big wolfram alpha person either
i actually have already done all the way to calc 4
finished it all up
but my girfrield just got into uni and she is taking calc 1
so im revisiting everything again
and as a good calc 1 student i remember almost nothing
haseeb
sorry that was bothering me
np
well, you know your partial derivatives then, so that's what happened :P
this is very real
i think for your limits question you should make another post
yeah theres no hard rule but seems different enough of a q for me
calc 1 was such a nightmare....
its quite ironic that calc 4 was actually the easiet
lol that's definitely different to my experience 😅 i think i remembered the most out of calc 3
calc 3 was my favorite but
calc 4 was easier
i liked sums and series and such
dont actually remember much from calc 4 but i got a 9.2 or smth in my final grade
just remember it being chill
hopefully i havent forgotten it qwbjhenqweqw

a useful website i found
Welcome to my math notes site. Contained in this site are the notes (free and downloadable) that I use to teach Algebra, Calculus (I, II and III) as well as Differential Equations at Lamar University. The notes contain the usual topics that are taught in those courses as well as a few extra topics that I decided to include just because I wante...
how do i change the tags to solved again
