limit as x approaches 0 of (-2x^2)/(x^2)

解答

x \to 0 lim (\frac{- 2 x ^{2}}{x ^{2}})

- 2

求解步骤

x \to 0 lim (\frac{- 2 x ^{2}}{x ^{2}})

\frac{- 2 x ^{2}}{x ^{2}} = - 2

= x \to 0 lim (- 2)

x \to a lim c = c

= - 2

x \to 0 + lim \frac{( ( ln ( x ) ) ^{2} )}{ln ( sin ( x ) )}

x \to \infty lim (3^{x} x!)

x \to 1 lim (e^{\frac{1}{x ^{2} - 1}})

x \to - 1 lim (\frac{e ^{x^{2}} - 1}{x})

x \to - 2 lim (x - x^{2})
