limit as x approaches 1+of 4x-2x^2

解答

x \to 1 + lim (4 x - 2 x^{2})

2

求解步骤

x \to 1 + lim (4 x - 2 x^{2})

代入值

x = 1

= 4 \cdot 1 - 2 \cdot 1^{2}

化简

= 2

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

d er i v a t i v e y = (5 x + 14)^{5}

(2 + y) d x - 3 (3 - x) d y = 0

\int 18 (200 + t)^{2} d t

x \to - 5 lim (- 9 x^{2} - 6 x - 9)
