limit as x approaches 2-of 4/((x-2)^5)

解答

x \to 2 - lim (\frac{4}{( x - 2 ) ^{5}})

- \infty

求解步骤

x \to 2 - lim (\frac{4}{( x - 2 ) ^{5}})

x

从左侧趋近于

2, x < 2 \Rightarrow (x - 2)^{5} < 0

分母从左侧趋近于 0，为负值

= - \infty

y^{^{'}} - y = 4 sin (3 t)

in v erse l a pl a ce \frac{1}{s - 1}

n = 4 \sum \infty \frac{1}{( n ) ( n + 1 )}

\int_{0}^{x} \frac{1}{( 1 - x )} d x

x \to 0 lim (\frac{1}{1 - e ^{x}})
