limit as x approaches 0 of x/(-14x^4+5x)

解答

x \to 0 lim (\frac{x}{- 14 x ^{4} + 5 x})

\frac{1}{5}

十进制

0.2

求解步骤

x \to 0 lim (\frac{x}{- 14 x ^{4} + 5 x})

化简

\frac{x}{- 14 x ^{4} + 5 x} : \frac{1}{- 14 x ^{3} + 5}

= x \to 0 lim (\frac{1}{- 14 x ^{3} + 5})

代入值

x = 0

= \frac{1}{- 14 \cdot 0 ^{3} + 5}

化简

= \frac{1}{5}

\int \frac{y ^{2}}{1 + y ^{3}} d y
