Let y = x^2 + 3x
and the question is Find [itex]\frac{dy^2}{dx^2}[/itex]
then how do I understand this token? is it [itex]\frac{d(y^2)}{d(x^2)}[/itex]
or [itex]\frac{(dy)^2}{(dx)^2}[/itex] = [itex](\frac{dy}{dx})^2[/itex]
or what ?
BTW: it's not wrong written, namely, not [itex]\frac{d^2y}{dx^2}[/itex]
