斜率 (7,6),(-7,-7)

解答

斜率

(7, 6), (- 7, - 7)

m = \frac{13}{14}

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}) = (7, 6), (x_{2}, y_{2}) = (- 7, - 7)

m = \frac{- 7 - 6}{- 7 - 7}

整理后得

m = \frac{13}{14}

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

y^{^{''}} + 3 y^{^{'}} + 2 y = \frac{1}{1 + e ^{t}}

\int x 1 + x + \frac{x ^{2} + 4}{x - 1} d x

\frac{d}{d x} (x^{3} ln (x^{4} + 1))

\int_{2}^{x^{2}} cos (t^{2} + 1) d t
