limit as (x,y) approaches (0,69) of x^3y

解答

(x, y) \to (0, 69) lim (x^{3} y)

0

求解步骤

(x, y) \to (0, 69) lim (x^{3} y)

代入值

(x, y) = (0, 69)

= 0^{3} \cdot 69

化简

= 0

d er i v a t i v e 1 4^{x}

x \to - 2 lim (\frac{4 - x ^{2}}{2 + x})

d er i v a t i v e f (x) = 2 e^{x} + \frac{8}{3 x}

\int e^{y^{88}} d y

t an g e n t f (x) = 4 x^{3} - 7 x^{2} - 15 x + 10
