Best ResponseYou've already chosen the best response.1The easiest way to do this is to use implicit differentiation on it as it stands. You differentiate using the normal rules but you treat y as an unknown function of x. This means f(y) differentates to f '(y)*(dy/dx) by the chain rule. xy + x + y^2 = 6 First implicit differentiation gives [1*y + x*1*(dy/dx)] + 1 + 2y*(dy/dx) = 0 .....[from xy].....................[from y^2] You can rearrange this to give dy/dx = (function of x and y) Second implicit differentiation gives dy/dx + [1*(dy/dx) + x*(d2y/dx2)] + [2*(dy/dx)*(dy/dx) + 2y*(d2y/dx2)] = 0 ...................[from x*(dy/dx)]......................[from 2y*(dy/dx)] Now you replace each dy/dx by its function of x and y found above. Then rearrange it to give d2y/dx2 = (function of x and y).

Best ResponseYou've already chosen the best response.1Well, (x^2)y + x(y^2) = 6 d/dx[(x^2)y + x(y^2)] = d/dx (6)

Best ResponseYou've already chosen the best response.0you use the multiplication rule right? udv + vdu?

jamroz

Best ResponseYou've already chosen the best response.0x^2(1) + y(2x) = 2xy + x^2

hba

jamroz

Best ResponseYou've already chosen the best response.0then how did you get 2xy then dy/dx x^2?

jamroz

Best ResponseYou've already chosen the best response.0or do you get dy/dx and all that stuff in parenthasis because you're finding the d/dx of y

Best ResponseYou've already chosen the best response.1\[dy/dx(x^2)+2y(dy/dx)x = y^22xy\]

hba

Best ResponseYou've already chosen the best response.1\[dy/dx(x^2+2xy)=y^22xy\]

hba

Best ResponseYou've already chosen the best response.1So,\[\frac{ dy }{ dx }=\frac{ (y^2+2xy)}{x^2+2xy }\]

Best ResponseYou've already chosen the best response.0question, when using the product rule

jamroz

Best ResponseYou've already chosen the best response.0how do you know which one to put dy/dx with

jamroz

Best ResponseYou've already chosen the best response.0like when we had x^2y and got dy/dx(x^2) + 2xy

jamroz

Best ResponseYou've already chosen the best response.0why'd we put dy/dx with x^2 and not 2xy?

hba

Best ResponseYou've already chosen the best response.1Well Its Your Own Decision Whether to Put U first or V First If We talk about the formula

jamroz

Best ResponseYou've already chosen the best response.0okay but then which one do i put the dy/dx with?

jamroz

Best ResponseYou've already chosen the best response.0like the next problem is y2 = (x+1)/(x1)

jamroz

Best ResponseYou've already chosen the best response.0so would i do 2y (dy/dx) = vdu  udv/v^2

jamroz

Best ResponseYou've already chosen the best response.0so dy/dx2y = (x+1)(1)  (x1)(1) / (x1)^2

Best ResponseYou've already chosen the best response.0I'm here. I have a question on where to put the dy/dx when solving

jamroz
 3 years ago
Best ResponseYou've already chosen the best response.0right now i'm working on y^2 = x1/x+1

jamroz
 3 years ago
Best ResponseYou've already chosen the best response.0so i take dy/dx y^2 = (x+1)(1)  (x1)(1) / (x+1)^2 right?

jamroz

Best ResponseYou've already chosen the best response.0and the left side will equal 2y when i take dy/dx of it

jamroz

Best ResponseYou've already chosen the best response.0now where do i keep dy/dx, when solving?

Godsgirl

Best ResponseYou've already chosen the best response.1\[2y dy/dx = [(x+1)(x1)] /(x+1)^2 \]

jamroz
 3 years ago
Best ResponseYou've already chosen the best response.0so you keep dy/dx with the y on the left

jamroz
 3 years ago
Best ResponseYou've already chosen the best response.0but why? cause i had gotten that far, i just didn't know which side to leave dy/dx with?

hba
