斜率 sqrt(7x+11)(2.5)

解答

斜率

7 x + 11 (2.5)

\frac{8.75}{7 x + 11}

求解步骤

y = 7 x + 11 \cdot 2.5

要确定函数的斜率，对

7 x + 11 2.5

求导

\frac{d}{d x} (7 x + 11 \cdot 2.5) = \frac{8.75}{7 x + 11}

\frac{8.75}{7 x + 11}

\frac{d}{d x} f (x) = \frac{2}{x ^{2}} - 5 x

x \to \frac{π}{2} lim (\frac{x}{2})

t an g e n t y = tan^{2} (x), (- \frac{π}{4}, 1)

\frac{\partial}{\partial y} (\frac{8 x}{y})
