    confusing derivatives question, don't know which notation to preserve?-screen-shot-2014-04-19-20.55.07.png



    I'm not sure if {d}^{3}y is equal to {(dy)}^{3}

    and if {dx}^{2} means  dx . dx

    Re: confusing derivatives question, don't know which notation to preserve?

    ... they didn't teach you basic notation?


    $\dfrac {d^2 x}{{dy}^2}$ means the 2nd deriviative

    $\dfrac {d^3 x}{{dy}^3}$ means the 3rd derivative

    $\dfrac {d^n x}{{dy}^n}$ means the nth derivative

    if it's understood you are differentiating with respect to $x$ you can use shorthand notation

    $y'=\dfrac {dy}{dx}$

    $y''=\dfrac {d^2 y}{{dx}^2}$

    etc.
