斜率 y= 1/(x-2),\at x=6

解答

斜率

y = \frac{1}{x - 2}, at x = 6

解答

- \frac{1}{16}

+1

十进制

- 0.0625

求解步骤

y = \frac{1}{x - 2}

要确定函数的斜率，对

\frac{1}{x - 2}

求导

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

- \frac{1}{( x - 2 ) ^{2}}

确定

x = 6

时的

- \frac{1}{( x - 2 ) ^{2}}

的值:

- \frac{1}{16}

- \frac{1}{16}
