limit as x approaches-4 of 1/((x+4)^4)

解答

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

\infty

求解步骤

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

如果

x \to a - lim f (x) = x \to a + lim f (x) = L

则

x \to a lim f (x) = L

x \to - 4 - lim (\frac{1}{( x + 4 ) ^{4}}) = \infty

x \to - 4 + lim (\frac{1}{( x + 4 ) ^{4}}) = \infty

= \infty

\frac{d}{d x} (10 x + 4 y)

d er i v a t i v e 8 tan (2 x)

\frac{d}{d x} (x^{2} - 64)

x \to 28 lim (\frac{x ^{2}}{4} - \frac{7}{x})

\int_{- 27}^{8} \frac{1}{3 x} d x
