derivative of ln(x^2+2x+1)

Solution

\frac{d}{d x} (ln (x^{2} + 2 x + 1))

Solution

\frac{2}{x + 1}

Solution steps

\frac{d}{d x} (ln (x^{2} + 2 x + 1))

Apply the chain rule:

\frac{1}{x ^{2} + 2 x + 1} \frac{d}{d x} (x^{2} + 2 x + 1)

= \frac{1}{x ^{2} + 2 x + 1} \frac{d}{d x} (x^{2} + 2 x + 1)

\frac{d}{d x} (x^{2} + 2 x + 1) = 2 x + 2

= \frac{1}{x ^{2} + 2 x + 1} (2 x + 2)

Simplify

\frac{1}{x ^{2} + 2 x + 1} (2 x + 2) : \frac{2}{x + 1}

= \frac{2}{x + 1}
