sum from n=0 to infinity of (1/17)^n

解答

n = 0 \sum \infty (\frac{1}{17})^{n}

\frac{17}{16}

十进制

1.0625

求解步骤

n = 0 \sum \infty (\frac{1}{17})^{n}

使用几何级数审敛法:

\frac{17}{16}

= \frac{17}{16}

x \to 0 lim (\frac{sin ( 5 x )}{6 x})

d er i v a t i v e f (x) = 3 sec (5 x)

d er i v a t i v e \frac{1 - 6 t}{5 + t}

\int 11 tan^{4} (x se) c^{6} x d x

\frac{d}{d x} (1 - e^{3 x})
