limit as x approaches-1 of (2/3)^x

解答

x \to - 1 lim ((\frac{2}{3})^{x})

\frac{3}{2}

十进制

1.5

求解步骤

x \to - 1 lim ((\frac{2}{3})^{x})

代入值

x = - 1

= (\frac{2}{3})^{- 1}

化简

(\frac{2}{3})^{- 1} : \frac{3}{2}

= \frac{3}{2}

\int_{\frac{1}{2}}^{3} 4 x ln (2 x) d x

\frac{\partial}{\partial x} (x^{2} \cdot sin (2 y))

x \to 2 lim (x^{2} - 6 x)

y^{^{''}} + 5 y^{^{'}} + 4 y = - 18 t e^{4 t}

\frac{d}{d x} (x e^{- s i n (x)} - x)
