    Differentials

    Can anyone help.Im stuck on this question.


    Using differentials find \frac{dy}{dx} when \frac{y}{x}-ln(x)=ln(c)

    Hey hacker804.

    What exactly do you mean by differentials?

    You can find the derivative by re-arranging y as a function of x (and constants) and then taking the derivative or you can use implicit differentiation and get dy/dx on LHS with other expression on RHS.

    Re: Differentials

    I think the differential which is defined as dy=f^{'}(x)dx

    Re: Differentials

    y - x Ln (x) = x Ln (c) ; y = x Ln (x) + x Ln (c), Now differentiate w r t x we get
    dy/dx = Ln (x) + 1 + Ln (c)
    That is it
