Card 1 of 20
When differentiating a function of yyy with respect to xxx, what factor must be included?
A
−34-\frac{3}{4}−43
B
If yyy depends on xxx, then ddx(siny)=\frac{d}{dx}(\sin y)=dxd(siny)= cosydydx\boxed{\cos y\frac{dy}{dx}}cosydxdy.
C
For x=t2+1x=t^2+1x=t2+1 and y=t3−3ty=t^3-3ty=t3−3t, the gradient at t=2t=2t=2 is 94\boxed{\frac{9}{4}}49.
D
Include dydx\frac{dy}{dx}dxdy.
