I asked this question earlier this week, and the person that responded at that time, may not have understood my question so I am asking the tutors who are online now to please help me with this:

Use the quotient rule for differentiation to find derivatives in each of the following: The quotient rule provided to me is: If f(x) = u(x) / v(x), if all indicated derivatives exist, & if v(x) is less than equal to 0 (zero), then: f(x) = v(x) .u'(x) - u(x) . v'(x) over [v(x)]^2 : Please respond with all the steps. Thank you very much.

Use the quotient rule for differentiation to find derivatives in each of the following:

(a) f(x) = x^2-2 over x^2 +3

(b) f(x) = 2 sqrt x-4 over the sqrt x

(c) f(x) = X^3-x^2 over x^2-1

I wrote the problems out because the system does not allow me to us a fraction line.
