limit as x approaches 6-of cx^2+3x

解答

x \to 6 - lim (c x^{2} + 3 x)

36 c + 18

求解步骤

x \to 6 - lim (c x^{2} + 3 x)

代入值

x = 6

= c \cdot 6^{2} + 3 \cdot 6

化简

= 36 c + 18

d er i v a t i v e \frac{x ^{2}}{1 + x ^{2}}

\frac{1}{x ^{7}} y^{^{'}} = 15 + 12 y

x \to 2 lim (\frac{x - 2}{x - 1})

(x^{2} + 1) y^{^{'}} = - 4 x (y - 1), y (0) = 8

d er i v a t i v e f (x) = e^{3 x}
