maclaurin ln(x+1)

maclaurin

ln (x + 1)

n = 1 \sum \infty (- 1)^{n + 1} \frac{x ^{n}}{n}

Solution steps

Apply the Maclaurin Formula

= 0 + \frac{\frac{d}{d x} ( ln ( x + 1 ) ) ( 0 )}{1 !} x + \frac{\frac{d ^{2}}{d x ^{2}} ( ln ( x + 1 ) ) ( 0 )}{2 !} x^{2} + \frac{\frac{d ^{3}}{d x ^{3}} ( ln ( x + 1 ) ) ( 0 )}{3 !} x^{3} + \dots

Evaluate Derivatives

= 0 + \frac{1}{1 !} x + \frac{- 1}{2 !} x^{2} + \frac{2}{3 !} x^{3} + \frac{- 6}{4 !} x^{4} + \frac{24}{5 !} x^{5} + \dots

Refine

= x - \frac{1}{2} x^{2} + \frac{1}{3} x^{3} - \frac{1}{4} x^{4} + \frac{1}{5} x^{5} + \dots

The series sum representation

= n = 1 \sum \infty (- 1)^{n + 1} \frac{x ^{n}}{n}

\int \frac{4 x}{2 + 2 x ^{2}} d x

\int \frac{ln ( 6 x )}{x} d x

\int \frac{1}{( x ^{2} + a ^{2} ) ^{\frac{3}{2}}} d x

\int (cos (2 x) - sin (2 x))^{2} d x

\frac{d}{d x} ((4 x^{3} - 6) (4 x^{2} + 4))
