Best ResponseYou've already chosen the best response.0its \[x ^{2}y ^{2}=1 \] or \[xy ^{2}=1\]?

Jaweria
 2 years ago
Best ResponseYou've already chosen the best response.1its x\[its x ^{2}y ^{2}=1\]

nitz
 2 years ago
Best ResponseYou've already chosen the best response.0OK....differentiate both sides wrt to y using product rule:: \[x ^{2}(2y)+((y ^{2})2x (dx/dy))=0\]

Best ResponseYou've already chosen the best response.0so tell me from above equation what would be dx/dy?

AravindG
 2 years ago
Best ResponseYou've already chosen the best response.1just solve for dx/dy after you applied product rule which will be .....

Best ResponseYou've already chosen the best response.1\[y^2=\frac{ 1 }{ x^2 }\]

Jaweria

Best ResponseYou've already chosen the best response.1how did you get \[X ^{2}\]

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Do you know how to differentiate explicitly?

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1You don't know that ???? \[x^2=\frac{1}{x^2}\]

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1So now, do you know how to differentiate explicitly?

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1That means you differentiate boths sides at the same time.

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Okay. Give it a shot and tell me what you get. Remember, when you differentiate the y part, you also have to attach a dy/dx.

Jaweria
 2 years ago
Best ResponseYou've already chosen the best response.1is it \[\frac{ y }{ x}\]

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Nope. Show me what you did as your first step.

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1I gave you this to differentiate. \[y^2=x^{2}\]

Jaweria

Best ResponseYou've already chosen the best response.1I did like this:dw:1359271872658:dw

Azteck

Best ResponseYou've already chosen the best response.1Then what's your next step.

Jaweria
 2 years ago
Best ResponseYou've already chosen the best response.1then I canceled \[Y ^{2} which became Y and Then I can canceled X ^{2} and \it became x\]

nitz

Best ResponseYou've already chosen the best response.0u have any doubt in my way......should i explain?

Jaweria

Best ResponseYou've already chosen the best response.1lolz right now I dont have any doubt at anyone I just need help very badly :(

Azteck

Best ResponseYou've already chosen the best response.1When you differentiate y^2, you get 2y?

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1and when you differentiate x^{2}, you get 2x^{3}

Jaweria
 2 years ago
Best ResponseYou've already chosen the best response.1Yes I did a mistake for X though but I couldnt understand Y one

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1That's exactly the same as differentiating y^2. What are you doing?

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1\[2y\times \frac{ dy }{ dx }=\frac{ 2 }{ x^3 }\]

Jaweria
 2 years ago
Best ResponseYou've already chosen the best response.1sorry one question that why there is

Jaweria
 2 years ago
Best ResponseYou've already chosen the best response.1Sorry but i have a question that how you got X^3

nitz
 2 years ago
Best ResponseYou've already chosen the best response.0\[(2x ^{2}y)=(2xy ^{2})(dx/dy)\] \[dx/dy=(2x ^{2}y)/(2xy ^{2})\] dx/dy=x/y

Best ResponseYou've already chosen the best response.1thanks Nitz for this :)

Jaweria

Best ResponseYou've already chosen the best response.1Aztec actually the answer I am having from the professor is matching with Nitz

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1@Jaweria, do you have an answer sheet or something?

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Ah okay. I can see that because you differentiate straight away. I moved the x^2 to the other side. Somehow that affected it.

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1nitz just differentiate straight away using the product rule.

Jaweria
 2 years ago
Best ResponseYou've already chosen the best response.1but as Nitz just explained I am little bit confused there that how he is getting 2\[2X ^{2}Y\] isnt that when you get 2X then you dont need \[2X ^{2}\]

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Don't you know how to do the product rule?

Jaweria
 2 years ago
Best ResponseYou've already chosen the best response.1I have it on my notes and I am still trying to learn this is my first homework of this Calculus class

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1What's the answer say in your sheet, Does it say x/y or y/x?

Jaweria
 2 years ago
Best ResponseYou've already chosen the best response.1it says \[\frac{ y }{ x }\]

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1He did dx/dy. You want dy/dx

Jaweria
 2 years ago
Best ResponseYou've already chosen the best response.1yeah but I dont think so that really matters you can do either way

Jaweria
 2 years ago
Best ResponseYou've already chosen the best response.1so its just we are flipping dy/dx instead of dx/dy

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1\[u=x^2\] \[u'=2x\] \[v=y^2\] \[v'=2y\] \[\frac{ dy }{ dx }=(u'\times v)+(u\times v')\]

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Sorry about that. \[0=2xy^2+2x^2y(\frac{dy}{dx})\]

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1When you differentiate y^2 you would write dy/dx next to it.

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Then you make dy/dx as the subject.

Azteck
 2 years ago
Best ResponseYou've already chosen the best response.1Okay. last one. And you can try and finish the others yourself using what you got from here.

Best ResponseYou've already chosen the best response.1try using draw button i will check :)

Jaweria

Best ResponseYou've already chosen the best response.1I know I ll get stuck again :( but I am trying

AravindG

Best ResponseYou've already chosen the best response.1try ! try you will succeed ! :)

Jaweria

Best ResponseYou've already chosen the best response.1ok first step so far: dw:1359274476783:dw

Best ResponseYou've already chosen the best response.1can you write thhird term again ? i cant see it clearly

AravindG
 2 years ago
Best ResponseYou've already chosen the best response.1i mean third term fully from y^2 sec^2 x

AravindG

Best ResponseYou've already chosen the best response.1and why do you have 2 equal signs ?

Jaweria
 2 years ago
Best ResponseYou've already chosen the best response.1I put X after equal sign because thats also in the question

AravindG
 2 years ago
Best ResponseYou've already chosen the best response.1for x diff with respect to y it will be simply dx/dy isnt it?

Jaweria
 2 years ago
Best ResponseYou've already chosen the best response.1yeah thats what I pot in paranthesis next to the X

AravindG
 2 years ago
Best ResponseYou've already chosen the best response.1you wrote dy/dx there?

AravindG
 2 years ago
Best ResponseYou've already chosen the best response.1what was the question ?

AravindG
 2 years ago
Best ResponseYou've already chosen the best response.1what i think is your question is \[y^2 \tan(x)=x \]

Jaweria
 2 years ago
Best ResponseYou've already chosen the best response.1sorry what is equal to dy/dx?

AravindG
 2 years ago
Best ResponseYou've already chosen the best response.1we just diff with respect to dy the whole equation

AravindG
 2 years ago
Best ResponseYou've already chosen the best response.1so why do you think dy/dx will appear?

Jaweria
 2 years ago
Best ResponseYou've already chosen the best response.1so the way i did is that wrong?

AravindG
 2 years ago
Best ResponseYou've already chosen the best response.1if you wanted dx/dy I believe my method is enough ...

AravindG
 2 years ago
Best ResponseYou've already chosen the best response.1i will be glad if someone verifies this bcoz i have not done differentiation for a while :P

AravindG
 2 years ago
Best ResponseYou've already chosen the best response.1dunno , maybe he is away

AravindG
 2 years ago
Best ResponseYou've already chosen the best response.1have patience :) in the meantime try to work on other questions .BEST OF LUCK !

Jaweria
 2 years ago
Best ResponseYou've already chosen the best response.1i have an answer sheet though

Jaweria
 2 years ago
Best ResponseYou've already chosen the best response.1alright then i ll work on them :)

AravindG
 2 years ago
Best ResponseYou've already chosen the best response.1ok whats the answer you have for this question ?

Jaweria
 2 years ago
Best ResponseYou've already chosen the best response.1its \[(1y ^{2}\sec ^{2}x)/2y \tan (x)\]

AravindG
 2 years ago
Best ResponseYou've already chosen the best response.1in btw i frgt to add tan x here dw:1359276176708:dw

Jaweria
 2 years ago
Best ResponseYou've already chosen the best response.1ahan thats what I was thinking

AravindG
 2 years ago
Best ResponseYou've already chosen the best response.1i get dx/dy as reciprocal of your answer...are you sure the question asks for dx/dy ?

Jaweria
 2 years ago
Best ResponseYou've already chosen the best response.1nope its asking for dy/dx

AravindG
 2 years ago
Best ResponseYou've already chosen the best response.1then my working is right !! :)

AravindG
 2 years ago
Best ResponseYou've already chosen the best response.1solve for dx/dy from my working...dy/dx=1/dx/dy
