Best ResponseYou've already chosen the best response.3??? \[y^2=cx+\frac{1}{8}c^3..............y=2xy'+y^2(y')^3\] or \[y^2=cx+\frac{1}{8c^3}..............y=2xy'+y^2(y')^3\]

Best ResponseYou've already chosen the best response.3so we are differentiating? one part of the equation with the fraction is still confusing.

Best ResponseYou've already chosen the best response.3so in the end we should have something like \[y=2xy'+y^2(y')^3 \]?

Best ResponseYou've already chosen the best response.3could you rewrite the first equation.. it's the fraction portion that is making me lost. I don't know if \[c^3y \] is in the denominator or the numerator

Best ResponseYou've already chosen the best response.3_! \[y^2=cx+\frac{1}{8}c^3. \]

Best ResponseYou've already chosen the best response.3omg I apologize the latex is crazy dw:1436693748089:dw

Best ResponseYou've already chosen the best response.3so we let the x and y be the variables and we treat c as a constant.

Best ResponseYou've already chosen the best response.3well on the farthest term the one with the 1/8c^3 if c is a constant and if all numbers are constants.. we will just have 0

Best ResponseYou've already chosen the best response.3do you know the derivative of y^2 ?

UsukiDoll

Best ResponseYou've already chosen the best response.3hmm... I would just leave it as 2y unless we are using implicit differentiation as well?

Best ResponseYou've already chosen the best response.3what about the derivative of cx?

UsukiDoll

Best ResponseYou've already chosen the best response.3let's see... product rule is f(x)g'(x)+f'(x)g(x) so we let f(x) = c and g(x) = x what is the derivative of f'(x) and what is the derivative of g'(x) ?

UsukiDoll

Best ResponseYou've already chosen the best response.3well .. the derivative of g(x) is 1 yes.. c(1) + that part is correct so for f'(x)g(x) f(x) = c and g(x) = x so we leave g(x) alone and take the derivative of f(x) = c. Since c is a constant, the derivative is 0 so we have c(1) +x(0) c+0 c

Best ResponseYou've already chosen the best response.3why is 1/8c^3 still there? a number like 1/8 is just a constant and c^3 is a constant too? I'm lost as the hills XD

Best ResponseYou've already chosen the best response.01/8c^3 is not a constant

Best ResponseYou've already chosen the best response.31/8 is a number... numbers are constants... derivatives of any number go to 0.

Best ResponseYou've already chosen the best response.3hmmm is c also treated as a variable? I can't even...

UsukiDoll

Best ResponseYou've already chosen the best response.3usually x and y are variables and anything but those letters are treated as a constant...

Best ResponseYou've already chosen the best response.3in the end we are supposed to have x's and y's somehow.. so that c has to be treated as a constant.

UsukiDoll

Best ResponseYou've already chosen the best response.3like... maybe factor one c out to make it like \[y^2 = c(x+\frac{1}{8}c^2) \]

UsukiDoll

Best ResponseYou've already chosen the best response.3then differentiate...

UsukiDoll

Best ResponseYou've already chosen the best response.3like we know that the derivative of \[y^2 \rightarrow 2y y'\] and then product rule for c()

Best ResponseYou've already chosen the best response.1what is mean of ODE ??

UsukiDoll

Best ResponseYou've already chosen the best response.3ODE means an ordinary differential equation...

Best ResponseYou've already chosen the best response.3\[y^2 dy = c(x+\frac{1}{8}c^2) dx\] if it's a separable equation, then we have to integrate both sides.

Best ResponseYou've already chosen the best response.1oh!! so we are given \[y=2xy' +y^{2}(y')^{3} and y ^{2}=cx+1\div8c ^{3} is \it ???\]

UsukiDoll
 one year ago
Best ResponseYou've already chosen the best response.3@sohailiftikhar supposedly we are differentiating \[y^2=cx+\frac{1}{8}c^3.\] and by doing that we get to \[y=2xy'+y^2(y')^3 \]

sohailiftikhar

Best ResponseYou've already chosen the best response.1just put value of \[y ^{2}\] in equation of y then take derivative of it ...

Best ResponseYou've already chosen the best response.3and with vague instructions, I can't go further... it's like hello I'm not a mind reader like what does the question want really?

Best ResponseYou've already chosen the best response.1I think we are give two equations and we have to find dy/dx
