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

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

Solution steps

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

Apply exponent rule:

a^{b} = e^{b l n (a)}

(x^{2} + 1)^{x + 1} = e^{(x + 1) l n (x^{2} + 1)}

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

Apply the chain rule:

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

= e^{(x + 1) l n (x^{2} + 1)} \frac{d}{d x} ((x + 1) ln (x^{2} + 1))

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

= e^{(x + 1) l n (x^{2} + 1)} (ln (x^{2} + 1) + \frac{2 x ( x + 1 )}{x ^{2} + 1})

e^{(x + 1) l n (x^{2} + 1)} = (x^{2} + 1)^{x + 1}

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

n = 0 \sum \infty n (\frac{3}{4})^{n}

\frac{\partial}{\partial y} (\frac{- y}{( x ^{2} + y ^{2} )})

f (x) = (ln (x + 1))^{2} - e^{x^{2}}

\int \frac{( z + 2 )}{z ^{2} + 3 z - 1} d z

\int t sin (π t) d t
