    help with diff equation with respect to squareroot

    Hi,
    i am challenged with a problem that is with respect to squareerootr
    d(squarroot x) = f(x)dt + f(x)dX ( it is a stochastic equation so not a regualre ODE).

    i really have a hard time knowing how to be able to treate this squareroot. If i square the whole left side do i get dx? or what are the rules regaring this?
    any advice would be helpful. Is there anyway i can get rid of the squareroot?

    best, busan

    Your question is basically: What is the differential of \sqrt{x}?

    So the place to start with is the derivative. What is \frac{d}{dx} \sqrt{x}?
