Quotient Rule Formula

In calculus, Quotient rule is helps govern the derivative of a quotient with existing derivatives. There are some steps to be followed for finding out the derivative of a quotient.

Now, consider two expressions with is in $\frac{u}{v}$ form q is given as quotient rule formula.

Question: Differentiate $\frac{2}{x+1}$ ?


Given equation is:

\(\begin{array}{l}\frac{d}{d x}\left(\frac{u}{v}\right)=\frac{d}{d x}\left(\frac{2}{x+1}\right) \\ =\frac{(x+1) \frac{d}{d x}(2)-2 \frac{d}{d x}(x+1)}{(x+1)^{2}} \\ =\frac{(x+1) \times 0-2(1)}{(x+1)^{2}} \\ =\frac{-2}{(x+1)^{2}}\end{array}\)
