    Solving an equation

    Hi, I have this equation

    x.f(x)=A

    where f(x) is a complicated function of x and A is constant. Is there any simple way to find x? At the moment I use trial and error to find x. Thanks.

    Re: Solving an equation

    You could use a root-finding technique such as Newton's method to approximate x.
