What should be added to the product of (x^2 + xy - y^2 ) and (x^2 - xy + y^2 ) to get x^2 y^2 ?+xy+y= 1,find the value of y'''at the point where x= 1. The student who asked this found it Unhelpful.If xy + 9e^y = 9e, find the value of y'' at the point where x = 0. Okay so first I found the first derivative using implicit differentiation and I got: [itex]y'=\frac{-y} First, are we agreed that y = 1 for x = 0 ? (I want to be careful, since you only have one attempt left on your computer-problem system.)x2 - xy + y2 = 21 x2 + 2xy - 8y2 = 0. The absolute value of x in the second equation above gives two cases for the values of y Not all combinations of these x-value and y-values are solution points. Don't be sloppy; write the solution out correctly.x2+xy+y3=1. (if x is 1). 1×2+1×y+y×3=1.

Yes I'm conscious I posted this but I did earlier than adding these kind of main points and I can't wait for it to head off grasp... This is the question I will not seem to determine easy methods to do. If $x^2 + xy + y^3 = 1$, find the value of $y'''$ at the point where $x = 1$.

I need help with this because my instructor barely speaks English and doesn't answer questions.. Therefore I'm having a good looking time attempting the homework. What I believe I've been in a position to take action some distance is take the first by-product then setting $x=1$ $$ y' =\frac -2 y+3y^2 $$

Then looking to take the 2nd spinoff the usage of the quotient rule.. $$ y'' = \frac (y+3y^2)(0)-(-2)(y+3y^2)' (y+3y^2)^2 $$ $$ (y+3y^2)' = (1)\left(\fracdydx\right)+6y\left(\fracdydx\right) = \frac-2y+3y^2+\frac-12yy+3y^2 = \frac-2-12yy+3y^2$$ $$ y''=\frac0-(-2)\left(\frac-2-12yy+3y^2\proper)(y+3y^2)^2 = \frac -\frac 4+24y y+3y^2(y+3y^2)^2=-\frac 4+24y y+3y^2*\frac1(y+3y^2)^2$$ $$ y'' = \frac 4+24y (y+3y^2)^3 $$ At this point, I'm now not certain it this is right.. But I went and tried for the third with more quotient rule! $$y'''= \frac(y+3y^2)^3(24)\left(\fracdydx\proper)-(4+24y)\left((y+3y^2)^3\proper)'(y+3y^2)^6$$ Before I will finish that downside I want the spinoff of $(y+3y^2)^3$... I imagine for this I need to use chain Rule.if $f(x)=x^3$ then $f'(x)=3x^2$ If we then let $g(x) = y+3y^2$ then $g'(x) = 1+6y$ leaving us with... $ (y+3y^2)^2*(1+6y)$$ Plugging that again in to the leisure of the downside we get... $$y'''= \frac(y+3y^2)^3(24)\left(\fracdydx\right)-(4+24y)\left(3(y+3y^2)^2*(1+6y)\right)\left(\fracdydx\proper)(y+3y^2)^6$$ factoring out a $(y+3y^2)^2$ I am getting $$y'''=\frac(y+3y^2)^2\left(y+3y^2)(24)\left(\fracdydx\proper)-(4+24y)\left(3(1+6y)\proper)\left(\fracdydx\proper)\proper)(y+3y^2)^6$$ canceling out for... $$y'''=\frac\left(y+3y^2)(24)\left(\fracdydx\right)-(4+24y)\left(3(1+6y)\right)\left(\fracdydx\right)\right) (y+3y^2)^4$$ $$y'''=\frac24y(1+3y)\left(\fracdydx\proper)-12(36y^2+12y+1)\left(\fracdydx\proper) (y+3y^2)^4$$ $$y'''=\frac\frac-48y(1+3y)y+3y^2+\frac24(36y^2+12y+1)y+3y^2 (y+3y^2)^4=\frac\frac-48y(1+3y)+24(36y^2+12y+1)y+3y^2 (y+3y^2)^4$$ Then in spite of everything... $$y'''=\frac-48y(1+3y)+24(36y^2+12y+1)y+3y^2*\frac1(y+3y^2)^4$$ $$y'''=\frac-48y(1+3y)+24(36y^2+12y+1)(y+3y^2)^5 $$

You have $x^2 + xy + y^3 = 1$ and need $y'''(1)$. Differentiating, we've: $

{title}

{content}

x+y+xy'+3y^2y' = 0$$ Again: $

{title}

{content}

+y'+y'+xy''+6y(y')^2+3y^2y'' = 0 \implies \\implies 2 + 2y'+6y(y')^2+(x+3y²)y'' = 0$$ Yet once more: $

{title}

{content}

y''+6(y')^3+12yy'y''+(1+6yy')y''+(1+3y^2)y''' = 0$$

If $x = 1$, then $x^2+xy+y^3 = 1$ offers $y+y^3 = 0 \implies y(y^2+1) = 0 \implies y = 0$. In the first step, we get $

{title}

{content}

+y' = 0 \implies y' = -2$$ Now we sub. $x = 1, y = 0, y' = -2$ in the second step, to get: $

{title}

{content}

-4+y'' = 0 \implies y'' = 2$$ Plugging all in the closing step: $-48+2+y''' = 0 \implies y''' = 42.$$

Differentiating $x^2 + xy + y^3 = 1$ gives $

{title}

{content}

x + xy' + y + 3y^2y' = 0$$ Differentiating again gives $

{title}

{content}

+ xy'' + 2y' + 6y(y')^2 + 3y^2 y'' = 0$$ A 3rd time offers $$xy''' + 3y'' + 6(y')^3 + 18 y y' y'' + 3y^2y''' = 0$$ In the best equation, settign $x = 1$ and $y = 0$ offers $

{title}

{content}

+ y'= 0$$ Which solves to $y' = -2$. Inserting into the 2nd equation gives $

{title}

{content}

+ y'' - 4 = 0$$ This solves to $y'' = 2$. Putting into the 3rd equation provides $$y''' + 6 - 48 = 0$$ This solves to $y''' = 42$.
