.

Use the formula for differentiating of a ratio of two functions (u/v)' = (u'v - uv')/(v^2). Take u(x) = x, v(x) = x+1.

Happy differentiating, dear Calculus student (!)

In many cases, finding the derivative is easier if you write the given function in a different form. It's a technique you might want to look at to see if it works for you.

In this example,

Now finding the derivative only uses the power rule:
