    Lightbulb Derivative

    Would just like to see if I did this right..Thanks!
    f(t)=2 √t^3 + 4/ √t- √2
    =3t^3+4/ √t^1/2-2^1/2
    =(t-1+2/t)
    =(-1)+(2/t)+(t)
    =(2/t)+(t)
    =2(1/t)+(t)
    =1-2/t^2

    Before I can check it , I need to know what it is. Is this what you have?

    2\sqrt{t^3}+\frac{4}{\sqrt{t}}-\sqrt{2}

    OK. Here we go............





    \frac{d}{dx}2t^{5/2}+4t^{1/2}-2^{-1/2}=5t^{3/2}+2t^{-1/2}-0=5t^{3/2}+2t^{-1/2}

    any questions?
