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

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

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

AravindG

Best ResponseYou've already chosen the best response.1sorry i gt disconnected :O

nitz

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

AravindG
 one year 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
 one year ago
Best ResponseYou've already chosen the best response.1Do you know how to differentiate explicitly?

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

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

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

Azteck
 one year 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
 one year ago
Best ResponseYou've already chosen the best response.1is it \[\frac{ y }{ x}\]

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

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

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

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

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

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

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

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

Azteck
 one year ago
Best ResponseYou've already chosen the best response.1Make dy/dx the subject.

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

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

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

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

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

Jaweria
 one year 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
 one year ago
Best ResponseYou've already chosen the best response.1Don't you know how to do the product rule?

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

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

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

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

Azteck
 one year ago
Best ResponseYou've already chosen the best response.1here's how you get y/x

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

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

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

Jaweria
 one year ago
Best ResponseYou've already chosen the best response.1one last question plzz

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

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

AravindG

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

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

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

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

AravindG
 one year 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
 one year ago
Best ResponseYou've already chosen the best response.1yeah thats what I pot in paranthesis next to the X

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

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

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

AravindG
 one year ago
Best ResponseYou've already chosen the best response.1dw:1359275616596:dw

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

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

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

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

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

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

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

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

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

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

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

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

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

AravindG
 one year 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
 one year ago
Best ResponseYou've already chosen the best response.1nope its asking for dy/dx

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

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