    Solving derivative with roots in denominator

    Homework Statement i have to get f'(x) using the limit definition of the derivative (lim as h approches 0 f(x)= (f(x+h) - f(x)) /h) and I don't know where to start. f(x)= 3/(sqrt(1+x^2) Homework Equations what do I do with the (sqrt(1+x^2) 3. The attempt at a solution I have...
