limit as x approaches 3-of 6/((x-3)^5)

解答

x \to 3 - lim (\frac{6}{( x - 3 ) ^{5}})

- \infty

求解步骤

x \to 3 - lim (\frac{6}{( x - 3 ) ^{5}})

x

从左侧趋近于

3, x < 3 \Rightarrow (x - 3)^{5} < 0

分母从左侧趋近于 0，为负值

= - \infty

a re a y = x^{2}, y = 3 - 2 x

\int \frac{4 x}{x ^{4} - 16} d x

d er i v a t i v e y = 2 cot (t) - e^{- t}

\int \frac{( 1 + x ) ^{3}}{x} d x

\frac{d y}{d x} = \frac{e ^{7 x}}{4 y ^{3}}
