Card 1 of 20
When yyy depends on xxx,
ddx(yn)=\htmlClass. \frac{d}{dx}(y^n)=\htmlClass{remove-space}{\text{[...]}}. dxd(yn)=\htmlClass.A
For x=f(t)x=f(t)x=f(t) and y=g(t)y=g(t)y=g(t),
dydx=\htmlClass. \frac{dy}{dx}=\htmlClass{remove-space}{\boxed{\frac{dy/dt}{dx/dt}}}. dxdy=\htmlClass.B
No gradient can be concluded without further analysis.

20y3dydx\displaystyle \mathbf{20y^3\frac{dy}{dx}}20y3dxdy
D
When yyy depends on xxx,
ddx(yn)=\htmlClass. \frac{d}{dx}(y^n)=\htmlClass{remove-space}{\boxed{ny^{n-1}\frac{dy}{dx}}}. dxd(yn)=\htmlClass.Card 1 of 20
