tangent f(x)= 6/x ,\at x=1

解答

切线

f (x) = \frac{6}{x}, at x = 1

解答

y = - 6 x + 12

求解步骤

找到切点:

(1, 6)

计算

f (x) = \frac{6}{x}

的斜率:

\frac{df ( x )}{d x} = - \frac{6}{x ^{2}}

EN : T i tl e G e n er a l Eq u a t i o n Sl o p e A t P o in t 2 Eq : m = - 6

找到斜率 m=

- 6

且穿过

(1, 6)

的直线:

y = - 6 x + 12

y = - 6 x + 12
