limit as x approaches 0+of (-1)/(14x)

解答

x \to 0 + lim (\frac{- 1}{14 x})

- \infty

求解步骤

x \to 0 + lim (\frac{- 1}{14 x})

x

从右侧趋近于

0, x > 0 \Rightarrow 14 x > 0

分母从右侧趋近于 0，为正值

= - \infty

\int (sec (\frac{x}{24}))^{2} tan (\frac{x}{24}) d x

h \to 0 lim (\frac{sinh ( x )}{h})

\int 2 cos (ln (x)) d x

\int sin (2 x^{2}) d x

y^{^{'}} + 4 x^{3} y = x^{3}
