斜率 y-3ln(x)-4=0

解答

斜率

y - 3 ln (x) - 4 = 0

\frac{3}{x}

求解步骤

y - 3 ln (x) - 4 = 0

对于

y - 3 ln (x) - 4 = 0

将

y

移到一边:

y = 3 ln (x) + 4

要确定函数的斜率，对

3 ln (x) + 4

求导

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

\frac{3}{x}

\int e^{7 x + 6} d x

s l o p e 7 x + 11 (2.5)

\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)
