斜率 (4,5),(9,11)

解答

斜率

(4, 5), (9, 11)

m = \frac{6}{5}

求解步骤

两点之间的斜率: 斜率

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

(x_{1}, y_{1}) = (4, 5), (x_{2}, y_{2}) = (9, 11)

m = \frac{11 - 5}{9 - 4}

整理后得

m = \frac{6}{5}

d er i v a t i v e \frac{d}{d x} (\frac{c}{x})

d er i v a t i v e \frac{d}{d t} (e^{t})

\int \frac{1}{( y ^{2} )} d y

d er i v a t i v e \frac{d}{d x} (\frac{( e ^{x} )}{x})

x \to \infty lim (\frac{x , x , ( x + x ^{2} )}{( 2 x - x ^{2} )})
