Best ResponseYou've already chosen the best response.0\[\frac{dy}{du}=2u\]\[\frac{du}{dx}=4\]\[\frac{dy}{dx}=\frac{dy}{du}\times \frac{du}{dx}=4\times2u=8u\]

Best ResponseYou've already chosen the best response.0can u guys show the working because i dont understand how u got that did u use the quotient rule to find dy/du

Best ResponseYou've already chosen the best response.0Just use the normal rule for differentiating polynomials to find dy/du and du/dx and the use the chain rule to find dy/dx.

Best ResponseYou've already chosen the best response.0ok i cant do it for you dy/dx =2u ,du/dx==4 and dy/dx= (dy/du)(du/dx)=2u(4)= 8u

Best ResponseYou've already chosen the best response.0but you problem reqiured dy/dx, du/dx and dy/du instead of using f(x)

Best ResponseYou've already chosen the best response.0ok if you want to use functions dy/du=f '(u)=2u du/dx=f '(x)=4 dy/dx=f '(u) f '(x)= 2u(4)=8u
