sum from n=1 to infinity of 1/(6^n)

n = 1 \sum \infty \frac{1}{6 ^{n}}

\frac{1}{5}

Solution steps

n = 1 \sum \infty \frac{1}{6 ^{n}}

n = k \sum \infty (a_{n}) = n = 0 \sum \infty (a_{n}) - a_{0} - a_{1} - \dots a_{k - 1}

= n = 0 \sum \infty \frac{1}{6 ^{n}} - \frac{1}{6 ^{0}}

n = 0 \sum \infty \frac{1}{6 ^{n}} = \frac{6}{5}

= \frac{6}{5} - \frac{1}{6 ^{0}}

Simplify

\frac{6}{5} - \frac{1}{6 ^{0}} : \frac{1}{5}

= \frac{1}{5}

\frac{\partial}{\partial x} (\frac{2 x}{x ^{2} + 7 y})

(1 - t) (1 + t^{2})^{- 1}

\int_{1}^{e^{2}} \frac{1}{x} d x

(2, - 3), (4, - 2)

f (x) = \frac{ln ( x )}{x ^{4}}
