sum from n=0 to infinity of e^{-6n}

解答

n = 0 \sum \infty e^{- 6 n}

收敛

求解步骤

n = 0 \sum \infty e^{- 6 n}

使用级数积分审敛法:

收敛

s l o p e (7, - 4), (8, 8)

\frac{d}{d x} (\frac{- ln ( 1 + 6 x )}{x})

\int 1 - 2 y d y

\frac{d}{d x} (arctan (g (x)) (x))

\frac{\partial}{\partial x} (3 sin (\frac{6 x}{y}))
